A new type of a laser hydrophone based on dynamic holograms, formed in a photorefractive
crystal, is proposed and studied. It is shown that the use of dynamic holograms makes it …

A mobile adaptive holographic laser hydrophone based on a dynamic hologram formed in a
photorefractive crystal is developed. The hydrophone sensitivity is to–163 dB (rel. 1V/μ Pa) …

In this paper, we developed and investigated an adaptive fiber-optic hydrophone based on
adaptive holographic interferometer which key element is dynamic hologram recorded in a …

We report a novel scheme of an adaptive optical microphone (AOM) based on two-wave
mixing in a photorefractive crystal. The sensitive element of the microphone is a thin metal …

We have proposed and analysed a scheme for the multiplexing of orthogonal dynamic
holograms in photorefractive crystals which ensures almost zero cross talk between the …

Characteristics of a holographic interferometer with photorefractive media that includes a
regime of real time registration of holograms are considered. The interferometer arranges an …

Successive amplification of a weak optical signal was realized experimentally in holographic
and quantum amplifiers. The signal was a coherent one with an intensity less than the actual …

The characteristics of dynamic transmission and reflection holograms are considered
theoretically. It is shown, using the specific example of holograms recorded in electrooptic …

Aa optical amplifier is a device where the coherent light beam intensity at the output exceeds
that at the input. A quantum amplifier generally contains on active medium where a …

Description of an original technique for control of the spectral response of narrow-band
optical filters in photorefractive crystals and results of experimental demonstration in both …
