Paper Abstract

We have developed a new device called electrically addressed cathode-ray tube coupled liquid crystal light valve as an input interface hardware in our hybrid pattern recognition system. A photorefractive bismoth silicon oxide crystal is used as dynamic holographic filter. An implementation of real-time hybrid optical pattern recognition using optical joint transform correlator which includes two type spatial light modulators, lase sources, CCD sensor and microcomputer is described. Theoretical analysis and initial experimental results are present.
