Lipinskii A. Y., Rudiakova A. N., Danilov V. V.

Keywords: photorefractive crystall, holographic correlator, acousto-optic correlation processor.

The paper presents review of optical and acousto-optic correlation processors that contain photorefractive crystals. Optical correlators are the efficient devices for the image recognition due to the parallel way high operation rate processing of significant data amount. The shift-invariant holographic joint-transform correlators, dynamic holographic correlator, acousto-optic correlation processors with memory were considered.
