A programmable real‐time optical joint transform correlator that generates sharper autocorrelation peaks is presented. A microchannel spatial light modulator is utilized as the threshold hard‐clipping square‐law device. A liquid crystal television is used to display the input target and reference image. The basic principle of the system and a preliminary experimental result are given.
