Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

We present a comprehensive analysis of the evolution of a grating envelope, in both
transmission and reflection geometry, during the erasure process in various readout …

A technique for quasi real-time holographic interferometry with reflection type objects is
presented. It is based on fast sequences of holographic double exposure interferograms …

Theoretical and experimental investigations of electric field selectivity of reflection volume
holograms in the geometry of the transverse electro-optic effect in LiNbO3 are presented …

We demonstrate a possibility to modify photorefractive properties of a ferroelectric crystal by
means of controlling the ferroelectric phase transition. This is shown by an example of co …

A general analytical model is developed for analysis of the diffraction properties of layered
structures of photorefractive gratings. With this model a simple closed-form expression is …

Electric-field multiplexing (EFM) results from the tuning of the effective wavelength of the
light beam inside a photorefractive crystal. This tuning results from the application of an …

Из (1) видно, что показатель преломления na является независимой переменной
подобно θ0 или λ. Таким образом, изменяя любую независимую переменную, мы …

We theoretically and experimentally analyze the angular selectivity curves of nonuniform
gratings recorded in a photopolymerizable silica glass. Due to the rigidity of this material …
