Paper Abstract

Enhanced spectra of an object in high-frequency components by a photorefractive BaTiO3 two-wave mixing are image on a phase-only filter of a reference object displayed by a liquid-crystal spatial phase modulator. Enhanced preprocessing of an object with phase-only filtering can be achieved a good discrimination ability. The experiments with the system are shown.
