Abstract

A new version of an experimental system of an optoelectronic hybrid optical parallel array logic system is constructed. The experimental system is composed of a two-dimensional correlator with selectable holographic filters and parallel electronic circuits. The system can process images consisting of 3 × 3 pixels at a time. Several types of processing are achieved both without and with dynamic selection of the holographic filters. On the experimental system, parallel operations of several logical functions and data transmission are demonstrated. Processing rates of iterative operation without and with filter selection are 278 and 143 frames/s, respectively.
