Abstract

Holographic image formation in photorefractive crystals with use of a complex object wave front is studied both theoretically and experimentally. It is shown that the optimal conditions for holographic recording of a complex image differ from those required when a plane wave front is used as an object beam. Experimental measurements of the hologram’s diffraction efficiency and the optical noise dependencies on the recording-beam polarization and intensity ratio are in good agreement with theory. An experimental approach designed to find the optimal configuration of optical elements in a holographic interferometer with a photorefractive crystal is presented.
