We present an experimental investigation of the phase conjugate reflectivity as a function of
angular deviation from collinearity of the pump waves in BaTiO 3. In that case of four-wave …

We propose and experimentally demonstrate two original methods for suppressing the
beam fanning noise of photorefractive amplifiers. The first one involves two wave mixing in a …

Spatial filtering and hologram formation using coherent and incoherent imaging techniques
are investigated experimentally in photorefractive materials. Spatial filtering involves …

The problems of image transmission via distorting media have been discussed in literature
and different methods have been suggested to solve these problems which include phase …

The processes of amplification of holographic grids connected with different components of
spacial spectrum of images in photorefractive crystals have been investigated theoretically …

Stable phase conjugate reflectivities as high as 60% have been achieved with back-seeded
stimulated photorefractive scattering (SPS) in a BaTiO 3 crystal having too small a gain …

A numerical simulation is reported of a one-pass system for suppression of dynamic
distortions, which is based on four-wave mixing of optical fields in photorefractive crystals. A …

We describe a real-time image-processing scheme that uses selective erasure of spatial
frequencies at the Fourier transform plane in an arrangement employing photorefractive two …

An optical processor for real-time generation of the Wigner distribution of complex amplitude
functions is introduced. The phase conjugation of the input signal is accomplished by a …
