Paper Abstract

The optimized matched spatial filter recording on the thermoplastic medium in terms of bias exposure and beam balance ratio for a high-frequency band is considered. Real-time recording of synthetic discriminant function based filters on the thermoplastic medium by using CRT that modulates a liquid crystal light valve is presented. An adaptive correlator system with holographic filter memory on the thermoplastic tape recorder is proposed.
