Complex Imaging of Photorefractive Records

Abstract

Commonly used diffraction method of photorefractive effect investigation does not give the complete information about properties of photorectrative record. Thus, the legitimate assumption aries that such a way of investigation cannot register manifestation of the all-possible mechanisms contributing to formation of the record in photorefractive medium. therefore, the combining of various ways of registering the record is required. In order to do so, except the classical diffraction investigation of photorefractive effect we used also imaging of refractive index distribution in the record by means of interference as well as imaging the transmittance of the sample in the place of the record. This contribution also presents some results obtained by methods of photorefractive record registration mentioned above. As the photorefractive mediumwas used Fe:LiNbO3 crystals.
