Journal ArticleDOI
Self adaptive high pass filtering using photochromic glass
TL;DR: In this article, an auto programmable spatial-filtering system using photochromic glass plate as a programmable SLM, illuminated by a single wavelength of light, is described.
Journal ArticleDOI
Partially coherent optical processor for enhancement of partial second order derivatives of an image: Analysis and implementation
TL;DR: In this article, an optical processor capable to perform partial second derivatives of an image working with partially coherent illumination is presented. But the method is based on the capacity of these devices to generate simultaneously a contrast reverted replica of the image displayed on it.
Journal ArticleDOI
Defect enhancement in periodic masks using 1/2-Talbot effect
Eugenio Garbusi,José A. Ferrari +1 more
TL;DR: In this paper, a defect enhancement method for periodic masks is presented, which uses the fact that periodic structures under coherent illumination generate replicas of itself displaced half period at certain distances (1/2-Talbot's length).
Journal ArticleDOI
Interferometric method for fiber diameter determination
José A. Ferrari,Erna Frins +1 more
TL;DR: In this article, a simple method for measuring the outer diameter of an optical fiber is presented based on observing the interference of light reflected in the fiber-air interfaces of a fiber side illuminated by a laser beam at oblique incidence.
