Paper Abstract

A microcomputer-based real-time programmable optical pattern recognition system utilizing two magneto-optic spatial light modulators (MOSLM) with a liquid crystal light valve (LCLV) is presented. The proposed system has the advantage of high speed processing capability. Since the proposed system utilizes a microcomputer-based concept, it offers the advantages of flexibility and versatility. With reference to the joint correlation property, the system is capable of performing cross-correlation with various reference image patterns in real-time. Thus this hybrid optical architecture can be applied to image correlation with a wide variety of reference images. With appropriate design of interfacing units, hardware and software, the system is capable of learning new patterns, once it has encounted. Simple experimental demonstrations of this proposed system is provided.
