The relatively slow response and erasure time (of the order of 1 sec at milliwatt-power levels
and decreasing with increasing incident power) of highly sensitive photorefractive crystals …

We have analytically solved the problem of N mutually incoherent pairs of beams in
photorefractive media, each pair of which shares a common grating. The results are applied …

A phase grating is produced in an iron-doped lithium niobate photorefractive crystal by two-
beam holographic configuration. Digital holography is used to investigate the two …

Difference holographic interferometry makes direct interferometric comparison possible by
using holographically reconstructed images of a master object for the illumination of a test …

Linear adaptive interferometers using diffusion holographic recording in cubic PRCs are
proposed and experimentally demonstrated for BTO. These devices are designed for linear …

Photochromic effects in crystals of photorefractive bismuth silicon oxide have been used for
the recording of permanent holograms. The combination of this permanent recording with …

The theoretical analysis of unstationary holographic recording in photorefractive crystals
under an external alternating electric field is presented. In particular, a step-like ac field …

A simple direct method for measuring the interference pattern of a light-to-recorded
hologram phase shift in photorefractive crystals is reported. The method is used for studying …

Oscillating behaviour of diffracted light on uniform illumination of holograms, recorded in
photorefractive crystals Bi 12 TiO 20, is observed experimentally. From the experimental …
