Paper Abstract

Conjugate image plane correlator with holographic disk memory is proposed. Optical correlation between the conjugate images reconstructed from holographic disk and input image on liquid-crystal television are executed under the rotation of disk. It was found that nevertheless of Fourier hologram recording with pseudorandom diffuser it is possible to take out the diffuser from original hologram recording scheme and get correlation signals between input and reconstructed conjugate images at output plane of two lens imaging system under image reconstruction process. The generation of conjugate replicas with high contrast causes an exact matching with input image which results in high recognition performance for autocorrelation signals. The real-time character recognition by optical parallel high- speed processing for 2D images with position normalization are demonstrated.
