▼ Abstract: The laser biospeckle is an optical interferometric phenomena that occurs when an incident light insides on an active biological material surface. The material activity can be originated from biological processes or even from some isolated physical phenomena. It does exist a group of components in a biological material which can change the biospeckle interference pattern. Many images processing techniques have been employed to quantify the activity level of a biological material and to correlate it with quality patterns. However, the techniques employed at this time for to quantify activity level and to evaluate seed quality, can not be employed to identify the components with acceptable accuracy. However, the identification and differentiation of these components is of fundamental importance to technique development applicable to a variety of situations as seed viability analysis, seed vigor, generating quick and non destructive, as well as capable of automation methods. Physical damages occurring by impact during product handling, insect attack and others do generate zones of low biological activities. By other side, seeds can exhibited zones attacked by fungi and other microorganisms holding high biological activities. Theoretical considerations support the possibility of identifying as well as mapping the phenomena originated from biological activities in seeds by inserting Wavelets Transform (TW) and Frequency Analysis in the image processing. Based on what it has been exposed before, the objectives of this research work can be summarized as to verify the potentiality of the Wavelets Transform (TW) applied to the laser biospeckle signal in indentifying and mapping phenomena associated to activities in seeds of Phaseolus vulgaris, L. The experimental setup included a monochromatic camera, a digital camera, a 632 red and 10 mW powered HeNe laser and a diode 632 nm and 5 mW powered. A tetrazolium (TZ) test was employed as a pattern test. The above described procedure generated digital maps of activity which were compared with the TZ. Results showed that the technique are able of identifying natural and mechanical bruising beans seeds. Artificialy generated thermal and chemical damages were identified as well. TW filtering techniques exhibits significant potentiality in indentifying high and low activities in beans seeds (Phaseolus vulgaris, L.) that can be correlated to damages and contaminations Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Dal Fabbro, Inacio Maria, 1944- (advisor), Fabbro, Inacio Maria Dal, 1944- (advisor), Braga Junior, Roberto Alves (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: The study of the behavior of building structures pass through the determination of the strain and stresses to evaluate the level of local and global security against the active actions. In the last years in Brazil, the extensometers have been commonly used to measure the strain at a specific single point. The optical extensometry presents itself as an alternative to this task by providing results for all points of measurement area (full field). The moiré techniques are the simplest of the optical extensometry and have the smaller indeces relating to noise. In this work, the sensitivity of mechanics (or geometric) interference of moiré technique reached levels that previously could only be obtained using interferometers (moiré interferometry). It is worth noting that interferometers are appliances that cost thousands of dollars. This task was made possible through the multiplication of fringes obtained through digital technology with application present in photography and digital image processing and proved able to measure deformations for micrometric from very low frequency cross gratings. This work is presented as digital geometric moiré technique (TMGD) because everything from image capture of specimen gratings until the generation of fringes was made by digital means and therefore does not fall within the classification set out in chapter which deals with the classification of moiré techniques. The result was something still unheard in civil engineering in Brazil, a low-cost technique, insensitive to vibrations and of the environment, moreover able to make measurements in plane surfaces without major apparatus. Findings show the applicability of the proposed method to measure strain and to analyze stresses in models and civil engineering structures Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Demarzo, Mauro Augusto, 1948- (advisor), Dal Fabbro, Inacio Maria, 1944- (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: Optical techniques have been used for both technical and scientific purposes. Optical techniques are usually characterized as being robust, inexpensive, non-invasive and non-destructive methods in to evaluate a diversity of materials which include agricultural derived products. It also shows applications ranging from engineering to human and animal health. In this doctoral dissertation, a new technique to evaluate some fruit properties is proposed. It combines two optical techniques (i.e. Biospeckle and Scan-line laser) whose applicability has been demonstrated as being alternative and innovative. The new proposed technique allows low-cost data acquisition, automation of the entire process, and a proper selection and classification method of vegetable bodies (e.g. fruits). Biospeckle allows obtaining information regarding the quality level of biological material into cellular structures. Scan-line laser enables the attainment of the object geometry on the axes Xi (i=1,2,3). The main purpose of this doctoral dissertation is to obtain a digital survey of biological materials (i.e. papaya, pear and tomato) integrating both geometric positioning and information concerning to its biological activity. The differentiation between different fruit shapes, fruit sorting by size, class, color and defects through image processing was also carried out. Thus it was also possible to observe fruits with surface irregularities, maturity, and mechanical damage, among others. This is the basis proposed for the automatic selection of agricultural products. The following materials were employed in the tests: a line-emitting diode laser with a wavelength of 632 nm, diffuse white light, CCD camera, computer, optical table, papaya, pear and tomato fruits and polystyrene spheres. The softwares utilized were: ImageJ, Octave, Matlab. A total of five computer programs were developed for the image processing procedures. Five experiments were performed: (1) Maturity Assessment of Fruits; (2) Three Dimensional Reconstruction and Mapping of Bioactivity; (3) Miscellaneous Format Detection; (4) Mapping Format, Class and Coloration; (5) Defect Detection. In Maturity Assessment there were correlated traditional methods to verify the maturity (the Hunter parameters L a b, pH, Total Soluble Solids (TSS), the relationship between Total Soluble Solids and Titratable Acidity (TSS/TA), Modulus of Elasticity, weight and diameter) and the optical technique Biospeckle by calculating the Moment of Inertia (MI). For the Three Dimensional Reconstruction the fruits were rotated by a stepper motor. At every step of the motor, the fruit was illuminated by the projected laser line and photographed in order to obtain both geometric and biospeckle data by the LASCA (Laser Speckle Contrast Analysis) method. The correlation between traditional methods for the maturity assessment and values of MI was analyzed. This doctoral dissertation shows that it is possible to evaluate the maturity of fruits through Biospeckle.
