Seismic interferometry is a technique by which the Green’s function (or impulse response) between two receivers can be acquired from the crosscorrelations of wavefield responses at these receivers. Recent developments of this method has led researchers to exploit active as well as passive seismic wavefields to retrieve surface wave Green’s functions by crosscorrelation. The primary objective of these applications has been to gain near surface resolution from the high frequency content of the active data while gaining greater depth resolution from the low frequency content of the passive data. In these applications however, a Green’s function is retrieved for each data type and therefore a matching filter or a form of joint inversion is required to benefit from the additional bandwidth of both data types. Interferometry by multidimensional deconvolution (MDD) is a relatively new method of Green’s function retrieval that provides several advantages over interferometry by crosscorrelation. This thesis proposes a new method of merging active and passive data during the process of MDD. A primary advantage of this method over the alternatives is that the source signatures are disregarded and only a single Green’s function with the combined characteristics of both the active and passive data is retrieved. Using numerical modelling it is demonstrated that a broadband Green’s function response can be retrieved from combined active and passive data without the need to compensate for the differences in source signatures or variations in amplitude. Merging active and passive data prior to deconvolution may in fact improve the retrieved response due to the additional illumination provided by the supplementary data. In addition to expanding the bandwidth of the retrieved response, this method is shown to be capable of using data from one source type to spatially infill gaps in illumination in another source type when the bandwidth of the two are comparable.

▼ The use of optics to detect ultra-subwavelength features embedded within structures is a hot topic for a broad diversity of applications like spectroscopy, nanotechnology, microscopy, and optical data storage discs. Conventional objective lens based optical systems have a fundamental limit on the best possible resolution of about 200 \u03b7m due to the diffraction of light as it propagates into the far-field. There already exist several near-field techniques with the capability to overcome this limitation, but each of these systems has certain drawbacks related to the complexity of the system or to limitations imposed by the system. A photonic nanojet is a very particular beam of light that can provide a practical way to overcome the diffraction limit inherent to far-field techniques. A nanojet is an electromagnetic field envelope formed on the shadow-side surface of a plane-wave-illuminated dielectric microsphere of diameter larger than the wavelength and with refractive index contrast relative to the background medium of less than 2:1. It can maintain a subwavelength transversal beamwidth for distances greater than 2 wavelengths away from the surface of the generating microsphere. This Dissertation provides a computational test of the hypothesis that the backscattered spectrum resulting from photonic nanojet illumination of a three-dimensional (3-D) dielectric structure can reveal the presence and location of ultra-subwavelength, nanoscale-thin weakly contrasting dielectric inhomogeneities within dielectric targets. The effect of surface roughness on the illuminated side of the target is analyzed, and targets ranging from simple dielectric slabs to complex biological cells are studied. The present work is performed through computational electrodynamics modeling based upon the rigorous, large-scale solution of Maxwells equations. Specifically, the 3-D finite-difference time-domain (FDTD) method is employed to test the above hypothesis.'

▼ The thesis reports on the evaluation and comparison of various signal processing algorithms for estimating the direction of arrival (DOA) of a high frequency (HF) beacon signal from a CubeSat in Low Earth Orbit (LEO). The DOA of the HF beacon signal is expressed in terms of the two angles, azimuth ( α ) and elevation ( ). The azimuth and elevation angles of the received HF signal are calculated from the phase differences between signals observed at three elements of an L-shaped crossed-loop antenna array. The algorithms which were evaluated are the Zero Crossing (ZC), Cross Correlation (CC), Fast Fourier Transform (FFT) and Cross Power Spectral Density (CPSD) algorithms. A theoretical analysis was done to demonstrate that the phase differences at the radio frequency (RF) of the beacon are propagated to the baseband signals. The algorithms were thus tested using simulated baseband signals as would be derived from the RF signals intercepted by the three elements of an L-shaped crossed-loop antenna array. Gaussian noise with a given signal-to-noise ratio (SNR) was added to the simulated baseband signals. The algorithms were implemented in MATLAB. The criteria for the selection of the best algorithm were accuracy and speed. The standard deviation (SD) of the azimuth and elevation errors was used to measure the performance accuracy of each algorithm, while the computational time for a given number of samples and runs was used to express the speed of each algorithm. First the ZC, CC, FFT and CPSD algorithms were evaluated for various SNR values, and compared with respect to SD of the azimuth and elevation errors. The analysis of the simulations demonstrate that the FFT and CPSD algorithms outperform the ZC and CC algorithms by estimating the DOA with a small SD of errors even at the low SNR of 0 dB, where the noise amplitude is the same as the signal amplitude. The ZC algorithm estimates the DOA with a large SD of error at low SNR due to multiple ZC points occurring during the same cycle. The ZC algorithm breaks down when the SNR decreases below 35 dB. The accuracy of the ZC algorithm depends on the method by which the ZC points are detected. The CC algorithm breaks down when the SNR decreases below 10 dB. The CPSD and FFT algorithms break down when the SNR decreases below – 20 dB. However, at a high SNR of 40 dB and above, all the algorithms estimate the DOA with a SD of error smaller than 1˚ for the azimuth and elevation. Next, the ZC, CC, FFT and CPSD algorithms were compared with respect to computation time. The FFT was found to be the fastest algorithm. Although the CPSD and the FFT algorithms reach the same accuracy in the estimation of the DOA, the FFT was selected as the optimum algorithm due to its better computation time. Recommendations are made regarding the implementation of the proposed algorithms for real signals from the HF direction finding (DF) array. At the time of submission of this thesis, such signals were not yet available.

▼ In a multi-component liquid mixture, the process of disassociation of the components induced by thermal gradient is called thermal diffusion or Soret effect. This effect plays a crucial role in separation of the components in hydrocarbon mixtures of oil. Accordingly, the main goal of this study is to experimentally investigate the Soret effect in binary and ternary hydrocarbon mixtures. Optical interferometry technique with Mach-Zehnder scheme was used to conduct the experiments. The interferometry techniques are not intrusive and the separation of the components in the mixture is not affected by the measurement instrument. A Soret cell is defined as a cubic cavity where the sample mixture is placed in it and, the separation of the components takes place in the cell by heating it from the above. Soret cells are used in convectionless experiments and natural convections are undesirable. The Soret cell used in space experiments was re-designed and optimized for ground-based experiments to avoid the natural convections. Computational studies were made on the both cells to obtain the temperature and velocity fields. Then a set of thermal diffusion experiments conducted in order to compare the performance of the cells. The results shows that the induced convective motions in the second cell are significantly weaker than those in the previous cell which is desirable. In the next step, the effect of the inclination of the cell on the thermal diffusion was studied. First numerical analysis was made to find the velocity and temperature fields in different inclinations and then a set of experiments was performed and the concentration distribution of the components in a binary mixture in different inclinations of the cell was found. Finally, ground based experiments were performed to study the thermal diffusion in five ternary hydrocarbon mixtures. Optical interferometry with Mach-Zehnder scheme using two laser sources with different wavelengths was used. The Soret information of one of the mixtures is available in the literature and this mixture was studied here to validate the present experimental setup.

▼ Freeform optical surfaces are creating exciting new opportunities in optics for design, fabrication, metrology, and assembly. While the term freeform is currently being applied over a broad range of surface shapes, in our research on imaging with freeform optical surfaces, a freeform is a surface whose sag varies not only with the radial component but also with the azimuthal component, φ, also known as a φ-polynomial optical surface. Interestingly, these surfaces are readily fabricated with techniques like single point diamond turning; however, challenges remain in their optimization during optical design and characterization after fabrication. </br> In this dissertation, we propose a more effective optical design approach based in nodal aberration theory that considers the aberrations induced by a φ-polynomial optical surface up to sixth order. Specifically, when a φ-polynomial overlay is placed on a surface away from the aperture stop, there is both a field constant and field dependent contribution to the net aberration field. These findings are validated through the design, implementation, and wavefront measurement of an aberration generating Schmidt telescope that employs a custom fabricated φ-polynomial plate. The measured wavefront behavior is in good agreement with the theoretical predictions of nodal aberration theory throughout the field of view. </br> The design methods are also applied to a specific example: a wide field, fast focal ratio, long wave infrared, unobscured reflective imager. The system employs three, tilted φ-polynomial surfaces to provide diffraction limited performance throughout the field of view. The surfaces were fabricated with diamond turning and a novel metrology approach based on an inteferometric null is proposed for characterizing the figure error of the fabricated surfaces. A mechanical design is also presented for the housing structure that simplifies the system assembly. The as-built optical system maintains diffraction limited performance throughout the field of view. </br> The work conducted in this dissertation provides a foundation for the efficient design of optical systems employing freeform surfaces and demonstrates that a system based on freeform surfaces is realizable in the long wave infrared and may be extended to shorter wavelength regimes.

▼ As the size of particulate matter decreases, individual particles are both more difficult to detect and show unique scattering properties. This thesis presents methods for optically detecting and imaging single nanoparticles and demonstrates the directional scattering properties of semiconductor nanoparticles. The first section describes a real-time interferometric method using multiple wavelengths to both detect and classify single nanoparticles in solution. A mixture of colloidal 60nm diameter Ag and 80nm diameter Au nanoparticles are identified within a 1 ms detection window. Detection sensitivity is limited by phase variations in the signal and two phase sensitive interferometric measurement techniques are proposed to improve the performance. In the second part of the thesis, GaAs nanoparticles are fabricated on a fused silica substrate using epitaxial lift-o and e-beam lithography. Recent theoretical work has predicted a suppression in the backscattering intensity in high refractive index semiconductor nanoparticles caused by interference between electric and magnetic dipole Mie resonances. Measurements of the fabricated GaAs particles show a suppressed backscattering at λ = 725nm agreeing with the modeled scattering properties and providing the first experimental verification of dipole interference in the visible spectrum. Potential applications for these highly directional scatterers include structured anti-reflection coatings and low-loss optical antennas for enhancing magnetic dipole interactions. Finally, a point-scanning confocal microscopy system is developed using a diamond turned ellipsoidal mirror, with a numerical aperture of ~1, as an illumination and collection objective. The focal properties are modeled using the Richards-Wolf integrals and alignment challenges are discussed. The imaging system wavefront performance is measured in an interferometer and the expected aberrated focal spot is simulated. A 40nm fluorescent nanoparticle is raster scanned through the focus to verify the measured performance. The tested system is the first confocal microscope implementing an ellipsoidal mirror as an imaging objective and provides high resolution, chromatic aberration free imagery of nanoparticles and nanostructures on opaque substrates. An additional spherical reference surface is proposed to monitor and simplify the system alignment.

▼ In the context of localized corrosion events such as pitting, the exposure of the test surface to bulk environments can result in the corrosion products being easily diffused into the bulk electrolyte solution. Hence, the products of localized corrosion reactions make limited impact on the overall corrosion process in such environments. However, the presence of a geometric confinement close to the test surface can entrap these products near the surface. As a result, a corrosion product that would otherwise reach insignificant concentrations can now accumulate to reach concentrations significant enough to possibly influence secondary chemical reactions within the geometric confinement. This can lead to the possibility of altering the corrosion reactions occuring within the confinement. The goal of this research was to investigate the role of geometric confinement on corrosion of aluminum alloy AA5083, sensitized at 175°C for 240 hours. This specific alloy was targeted because it has a favorable strength-to-weight ratio, but is susceptible to pitting as well as stress corrosion cracking. This research was pursued because a better understanding of the role of geometric confinement should improve upon our understanding of localized corrosion in general. It should also improve the ability to assess practical instances of corrosion attack where the environmental conditions are different from that of an ideal laboratory environment. This thesis approaches the problem statement in three main sections: First, a comprehensive analysis of the chemical composition within the crevice was performed using a host of tools such as electrochemical pH probes, custom-fabricated ionic conductivity meters, optical dissolved oxygen probes and inductively coupled plasma mass spectroscopy (ICP-MS). Based on these tests, a detailed understanding of the chemical make-up within the crevice was achieved. A substantially alkaline environment (with pH exceeding well over 9) was observed, along with depletion of dissolved oxygen. This suggested a cathodically driven corrosion reaction accompanied by oxygen reduction reaction within the crevice environment. Next, the practical implications of oxygen depletion on corrosion in geometric confinement were explored. A common occurrence of this phenomenon would be crevice corrosion. Here, a deep artificial crevice was created (1cm wide, 3cm deep, 150 microns thick), and was subjected to 1 molar sodium chloride solution for different time durations, lasting till 1 week. The surface damage was quantitatively characterized by using optical interferometry. Compared to the sample exposed to the bulk corrosion, the sample exposed to crevice corrosion showed a transition between the mode of corrosion attack. The bulk region was primarily subjected to pitting. While some intergranular attack was seen, it was not systemically present. In the crevice opening region, the attack was predominantly intergranular. In the deep interior of the crevice, the region was almost intact, with minimal surface damage …

▼ Current comparison methods for experimental and simulated holographic interferometric images are qualitative in nature. Previous comparisons of holographic interferometric images with computational fluid dynamics (CFD) simulations for validation have been performed qualitatively through visual comparison by a data analyst. By validating the experiments and CFD simulations in a quantifiable manner using a consistency analysis, the validation becomes a repeatable process that gives a consistency measure and a range of inputs over which the experiments and CFD simulations give consistent results. The quantification of uncertainty in four holographic interferometric experiments was performed for use in a data collaboration with CFD simulations for the purpose of validation. The model uncertainty from image-rocessing, the measurement uncertainty from experimental data variation, and the scenario uncertainty from the bias and parameter uncertainty was quantified. The scenario uncertainty was determined through comparison with an analytical solution at the helium inlet (height, x = 0), including the uncertainty in the experimental parameters from historical weather data. The model uncertainty was calculated through a Box-Behnkin sensitivity analysis on three imageprocessing code parameters. Measurement uncertainty was determined through a statistical analysis to determine the time-average and standard deviation in the interference fringe positions. An experimental design matrix of CFD simulations was iv performed by Weston Eldredge using a Box-Behnkin design with helium velocity, temperature, and air co-flow velocity as parameters in conjunction to provide simulated measurements for the data collaboration Data set. Over 3,200 holographic interferometric images were processed through the course of this study. When each permutation of these images is taken into account through all the image-processing steps, the total number of images processed is over 13,000. Probability distribution functions were plotted for each interference fringe order at each measurement height, making a total of 22 PDFs. Model, scenario, and measurement uncertainty was quantified in the experiments. The CFD simulations were performed. The final uncertainty attributed to the experiments resulted in a maximum uncertainty of -7.96 fringes. The largest contributor to uncertainty was the scenario uncertainty with measurement uncertainty as the second largest. The model uncertainty was very small and as such had the smallest contribution to the overall experimental uncertainty. In the future, the results of this study will be used in conjunction with the CFD simulations discussed and their attributed error in a data collaboration to determine Data set consistency for validation.

▼ Abstract: Two important issues in SAR interferometry (InSAR) are absolute phase and baseline estimation. The precise knowledge of these parameters is essential for the production of digital elevation models with high accuracy. The absolute phase estimation can be done in two steps. The first step performs the unwrapping of the phase, which retrieves the 2? multiples of the phase. The second step estimates the phase offset caused by a combination of errors in the acquisition system and in SAR interferometry (InSAR) processing. The baseline estimation determines the relative position of the slave antenna with respect to the master antenna (reference antenna). The contributions of this thesis consist in the design and implementation of three methods that use multiple antennas to address the above issues. The first method performs the unwrapping of the phase in a pixel based fashion, by iteratively unfolding the phase corresponding to each interferograma, followed by maximum likelihood fusion of the unwrapped phases. The second method refines the absolute phase estimation of the first step by incorporating a phase offset estimation based on multiple, noncollinear, antennas. This is achieved by minimizing the geometrical distortion (relative error) in the reconstructed digital elevation model induced by erroneous phase offsets in the interferograms. One advantage of this method is that it does not require the deployment of corner reflector in the area to be imaged. Lastly, the third method deals with baselines estimation. A baseline is determined by the relative positions of the slave and master antennas. The estimation is performed with a greedy stochastic algorithm of Monte Carlo type which uses corner reflectors with precisely known positions. A new position for the slave antenna is accepted when the mean square error of the corner reflector positions is reduced Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Costa, Max Henrique Machado, 1950- (advisor), Universidade Estadual de Campinas.

▼ In chapter 1, we determine the masses, radii and temperatures of the eclipsing binary V578 Mon, a detached system of two early B-type stars in the Rosette Nebula, to better than 5% accuracy. We compare these measurements to the stellar models of the Geneva, Utrecht and Granada group. We find all three sets of models marginally reproduce the absolute dimensions of both stars. However - there are some apparent discrepancies, and the Utrecht models worked best. We also compute the combined internal structure constants for V578 Mon. We find that the predicted internal structure constants of the Granada models fully agrees with our observations. In chapter 2, we present the results of a Hubble Space Telescope survey of the lowest mass brown dwarfs in the Pleiades. These objects represent the predecessors to T-dwarfs in the field. Using a new PSF-fitting technique, we are able to probe to 30 milliarcseconds, better than 2× the HST diffraction limit. We did not find any companions to our targets. Our survey is the first to attain the high angular resolution needed to resolve brown dwarf binaries in the Pleiades at separations that are most common in the field population. We constrain the binary frequency to be <26% at 2σ. This binary frequency is consistent with both younger and older brown dwarfs in this mass range and with brown dwarf formation models. Visible-light long baseline interferometry holds the promise of advancing a number of important applications in fundamental astronomy, including the direct measurement of the angular diameters and oblateness of stars, and the orbits of binary and multiple star systems. To advance, the field requires instruments capable of combining light from 6 telescopes simultaneously. In chapter 3, we present the Visible Imaging System for Interferometric Observations at NPOI (VISION) is a new visible light beam combiner for the Navy Precision Optical Interferometer (NPOI) that coherently combines light from up to six telescopes simultaneously. We detail the commissioning of VISION with laboratory and on-sky tests. We provide a new set of corrections for the power spectrum and bispectrum when using EMCCDs.

▼ This thesis is concerned with the design and building of a foot pressure system capable of measuring the pressure distribution underneath the diabetic foot. The system is developed to have a higher resolution and be more cost-effective than existing commercial systems. The biomechanics of the foot and ankle is explained in detail, providing an explanation for the relationship between high pressures and ulcerations. Various techniques of measuring foot pressure are reviewed, providing a thorough understanding of the advantages and disadvantages of each technique. The system developed uses the technique of interferometry, which is discussed in detail, explaining why the Fizeau Interferometer technique was chosen over other interferometer techniques. A number of materials were tested as to their suitability to be used as the pressure plate in the system i.e. compression/force relationship. From the results 'Perspex' was found to be the most suitable material. Two fringe-processing software packages were tested i.e. Fringe Processor 2 and Fringe Pattern Analysis (FRAN), with Fringe Processor 2 being chosen for this research. A graphical user interface for image display was created in order to display and analyse the various pressure images. Three prototypes were implemented. The first used a variation on the Fizeau interferometer, the second used a variation on the Twyman Green interferometer, whilst the third improved on the use of the variation of the Fizeau interferometer. By analysing the advantages and disadvantages of each prototype, the 3 rd prototype was chosen as the most suitable for achieving the aims and objectives of this research. This prototype was subjected to various tests i.e. resolution, measurable area, repeatability, calibration, short term reliability and sensitivity to heat. Various normal and pathological foot measurements were taken and analysed, and the effectiveness of the image display graphical user interface tested. The main contribution of this thesis is the use of interferometry to measure pressure. This in turn provides a foot pressure system, which has extremely high resolution and accuracy. The simple nature of the new pressure system also means that the entire system is very cost effective.

▼ Thermodynamical fluctuations impose random noise on the position of optical components. It is predicted that this thermal noise will limit the sensitivity of interferometric gravitational-wave detectors in their most sensitive frequency band. Thermal noise originating from optical coatings was first considered in the context of interferometric gravitational wave detectors. Its true significance was, however, only revealed after Y. Levin introduced a new method in 1998 to calculate the resulting phase noise of a laser beam reading out the position of a coated mirror. A result of this analysis is that the reflective optical coatings introduce a particularly large portion of thermal noise. ¶ As a consequence, coating thermal noise is expected to prevent the detection of the standard quantum limit; a limitation to the sensitivity of an interferometric measurement caused by quantum fluctuations in the optical field. Elimination of the coating thermal noise will increase the likelihood of the successful observation of the standard quantum limit, thus enabling the investigation of quantum noise in the regime of optical squeezing. This project investigated a means to eliminate the effects of coating thermal noise, with the design and characterisation of a highly reflective coating-free mirror. This mirror utilised the phenomenon of total internal reflection and the Brewster angle to reflect light without the use of coatings. The dimensions of the mirror were governed by its expected implementation in an experiment to measure the standard quantum limit. ¶ The design of the coating-free mirror undertaken as the initial part of this project is presented in detail. Once a CFM had been created according to this design, its spatial dimensions were measured. The weight of the mirror is 0.43 ± 0.01 g, well within the design goal of 0.5 g. ¶ In order to analyse the reflectivity of the coating-free mirror it was incorporated, together with a high quality conventional mirror, into a triangular ring cavity. This cavity was stabilised to the laser frequency by the Pound-Drever-Hall technique. This enabled the interrogation of the stable cavity properties by an AM-sideband transfer scheme. The reflectivity of the mirror was analysed for optimum rotational alignment and as a function of its rotational alignment angle. The maximum reflectivity deviated from the expected value calculated from the mirror design. Most of the excess loss was attributed to scattering due to surface roughness at the points of total internal reflection and a necessary deviation from the Brewster angle due to the geometry of the cavity combined with the flat front face of the coating free mirror. ¶ For optimum alignment a cavity finesse of about 4000 was measured, corresponding to a reflectivity of the coating free mirror of 99.89%. Thus, the objective of creating a highly reflective lightweight coating-free optic was achieved. The obtained reflectivity can be further increased by using a substrate that is super polished at…

▼ Quantum-enhanced interferometers utilize non-classical states of light in order to surpass the limitations imposed by classical physics on phase measurement sensitivity and resolution. We review key scientific developments in this growing field of research and derive fundamental metrology concepts, namely the Cramér-Rao bound and the Fisher information, which are used to analyze the metrological performance of quantum states of light. We propose a supersensitive quantum interferometry protocol that can be amplified to the macroscopic realm (i.e. the mean number of photons of the probe state can reach approximately 100,000 photons) using contemporary techniques of spontaneous parametric down conversion. The parity measurement on the output field asymptotically saturates the quantum Cramér-Rao bound, which scales like the Heisenberg limit. We uncover the role of photon statistics on phase sensitivity and rule out the necessity of mode entanglement for quantum-enhanced interferometry. Based on these insights we outline a practical metrology technique (independent of mode entanglement) that measures a phase delay of a single-mode anti-squeezing operation. This scheme can also be scaled macroscopically using contemporary techniques and is shown to significantly surpass the shot-noise limit (SNL) in the presence of realistic losses. Finally, the physical resources that enable quantum-enhanced interferometry is studied by analyzing the quantum Fisher information (QFI) using the first quantization and the second quantization formalisms of quantum mechanics. It is shown that increasing the intra-mode correlations of an interferometer (as quantified by the second order Glauber coherence function) can be conducive to attaining a quantum advantage in phase estimation; whereas, introducing mode entanglement can reduce phase sensitivity. Using the first quantization description, we derive a formula for the QFI that shows explicitly how the Heisenberg scaling term depends on particle entanglement.

▼ Pairing the information received from multiple telescopes to explore the universe is typically based on the interference phenomenon between amplitudes of light, rather their intensities. Brighter sources and larger telescopes allow for greater amounts of light to be collected, but do not specifically involve the intensity interference of electromagnetic fields. There is an alternate form of creating images of distant objects called Intensity Interferometry (II), which is less sensitive to atmospheric distortions and aberrations of telescope surfaces. The deficiencies of II are overcome as photo detectors become more sensitive and computers more powerful. In recognition of this possibility this dissertation investigates how the deformation of a large optical surface would influence the accuracy of II. This research first involved obtaining an understanding of the theoretical foundation of II and statistics (based on quantum mechanics) of photon correlations. Optical Ray-tracing and Finite Element Analyses were thereafter integrated to answer this question: how would the correlation of the intensity field change as a large light weight reflective structure deforms? Analytical models based on the theory of the deformation of shells were developed to validate the Finite Element Analyses. In this study a single focal parabolic reflector of an Intensity Interferometer (II) system is simulated. The extent that dynamic focal properties amongst a parabolic reflector change the statistics of the light at a detector is analyzed. A ray tracing algorithm is used to examine how the statistical variations of simulated monochromatic stellar light changes from the source to the detector. Varying the positions of the detector from the focal plane and the surface profile of the mirror develops a metric to understand how the various scenarios affect the statistics of the detected light and the correlation measurement between the source and detector. Photon streams are evaluated for light distribution, time of flight, and statistical changes at a detector. This research and analysis are used as a means to develop a tool to quantify how structural perturbations of focal mirrors affect the statistics of photon stream detections inherent in II instrumentation and science.'

▼ Light pulse atom interferometers have demonstrated remarkable sensitivity and stability for acceleration and rotation rate measurement. However, typical manifestations are designed for laboratory environments and thus rely on a fixed magnitude and direction of gravity, and limited ambient rotation rate. We have enhanced the application space of atom interferometers towards more dynamic environments, with special attention for inertial navigation. I present our work in the domain of short time-of-flight atom interferometry, whereby the magnitude of ensemble excursion is constrained. The limited interrogation time results in a significant loss of sensitivity. We recover a fraction of the lost sensitivity by operating with an enhanced duty-cycle and data-rate. To demonstrate this concept, we construct an atom interferometer accelerometer capable of operating at data-rates as high as 300 Hz with sensitivities at μg/rtHz levels, which represents a competitive figure for inertial navigation application. For the bulk of this work, we demonstrate a dual-axis sensor capable of simultaneous acceleration and rotation-rate measurements. The sensor relies on a technique we refer to as "ensemble exchange" which provides a high flux source of ultracold atoms by swapping atomic ensembles between two MOTs. We achieve a steady-state atom number of 7e6 atoms/shot using a minimal loading time of a few milliseconds each shot. Furthermore, we find this technique to be robust under dynamic conditions as large as 10 g of acceleration and 20 rad/s of rotation rate, representing a significant enhancement in ultra-cold atom sample preparation. The sensor achieves μg/rtHz and μrad/s/rtHz sensitivities, making this technique a compelling prospect for inertial navigation applications. Through the use of auxiliary cosensors and a real-time combinatorial loop with feedforward and feedback mechanisms, we demonstrate an unprecedented enhancement of the sensor dynamic range up to 20 mg. Finally, I will discuss a novel manifestation of short time-of-flight atom interferometry in a warm atomic vapor, which avoids the complication of cold sample preparation and has the potential for significantly simplified laser systems.

▼ A digital speckle-pattern interferometer was built utilizing a 100 x 100 element Reticon diode array interfaced to an HP-9836C desk-top computer. A single-mode optical fiber mounted in the center of the system's aperture stop creates a spherical-wave reference beam. Secondary interference fringes are calculated inside the computer by subtracting speckle patterns before and after a deformation, and squaring this difference. This technique has been shown superior to that of taking the absolute value of the difference. The traditional vibrational observation technique of low-pass filtering a single speckle pattern and squaring the result is emulated in software. It is compared to four other vibration observation techniques. A new technique records the self-interference terms in a reference frame, and subtracts these from the time-averaged vibration data. It provides very good fringe contrast for moderately unstable objects, as well as interferometers which have not been optimized to minimize self-interference terms. The best vibration fringe contrast is obtained by subtracting two time-averaged speckle patterns of a single object resonance. One exposure has a relative π phase-shift between object and reference beams to cancel self-interference terms. This last technique is not real-time; whereas, the new technique is. Double-exposure speckle interferograms are averaged using a technique which utilizes a stepping motor to change the object illumination angle. Results of averaging deformation measurements and double-exposure vibration techniques show a large increase in fringe contrast with an accompanying reduction in speckle noise. Quantitative measurements of object deformations is demonstrated by applying phase-shifting interferometry techniques. A deformation's phase is found by subtracting modulo 2π phases measured for each object state. Phase discontinuities are removed with the aid of noise reduction algorithms. Limitations are low intensity modulation as the phase is shifted, and speckle decorrelation during object deformation. It is shown that 10 waves of object deformation are measurable to λ/10 across the detector array. The double-exposure phase-measurement technique works well and is applicable to many different metrological measurements. To show the versatility of this technique, an optically smooth surface is contoured using two illumination wavelengths.
