Paper Abstract

A compact, FT lens binary joint transform correlator (BJTC) based on a high resolution ferroelectric liquid crystal, optically addressed spatial light modulator (FLC-OASLM) read in transmission mode is proposed. Experimental results of its implementation using two semiconductor lasers are presented. A binary and a gray scale driving operation of the SLM are introduced and good multiple object recognition capability at high frame rates is demonstrated.
