Paper Abstract

A programmable real-time optical joint transform correlator that generates sharper autocorrelation peaks is presented. In the system, a microchannel spatial light modulator (MSLM) is utilized as the threshold hard-clipping square-law device. A liquid crystal television (LCTV) is used to display input target and reference image at the input plane with a microcomputer. By using the feed-back loop, as depicted in the system schematic, the system would, in principle, offer adaptive processing capability. Basic principle of the system and a preliminary experimental result are given.
