摘要: We have built an optical VanderLugt-type correlator that uses two Epson liquid crystal televisions (LCTVs) separately generating the amplitude and phase modulation properties. The input scene is displayed in amplitudemostly regime on first LCTV. Thereafter a phase-only filter with different level of quantization addressed phase-mostly second To characterize this device, modulations were experimentally measured investigated pattern recognition application where grey-level scenes multilevel kinoforms are LCTVs.
