In this paper, Laser speckle image processing based on Fast Fourier Transform method for displacement measurement is presented. Capturing Laser speckle images before displacement and after displacement of the specimen is the technique involved in this mea... see more

Telah dilakukan penelitian dalam menginvestigasi kadar gula darah menggunakan metode Laser speckle Imaging, yang merupakan pencitraan dari peristiwa interferensi cahaya yang mengenai permukaan yang kasar. Penelitian ini memberikan suatu solusi alternatif ... see more

Este trabalho teve como objetivo estudar padrões do "speckle" em função da textura das madeiras Bowdichia virgilioides (sucupira), Swietenia macrophylla (mogno) e Balfourodendron riedeliaum (pau-marfim) e de Eucalyptus grandis. A análise do fenômeno ótico... see more

Additive manufacturing (AM) is a production technology where material is accumulated to create a structure, often through added shaped layers. The major advantage of additive manufacturing is in creating unique and complex parts for use in areas where con... see more

Bio-speckle can be used as a method for analysing the activity of biological materials illuminated with laser beam.  Physically, bio-speckles are the result of scattering of coherent light on moving particles inside living tissue.  Therefore, th... see more

Biospeckle is a phenomenon that interprets an optical pattern formed by illuminating a surface under changes with coherent light.  These patterns are usually analyzed by numerical as well as graphical methods.  Present work evaluated the applica... see more


We investigated whether the change in ocular blood flow, induced by hypo- and hypercapnia, is related to static visual acuity. Eleven healthy subjects (26±5 years) underwent three treatments. A three-treatment three-period crossover design was used. In th... see more
