Application of acousto-optic selectivity for optical image processing

Abstract

Results are presented of a theoretical study of optical image processing based on two-dimensional acousto-optic filtration of the spatial spectrum of images. Most attention is concentrated on the analysis on the analysis of the acousto-optic transfer function form and its dependence on crystal cut, geometry of acousto-optic interaction and ultrasound frequency. Results of computer simulation of acousto-optic spatial filtering are illustrated by the example of an object in the form of an amplitude grating. For this object, effects of image differentiation and integration are demonstrated.
