Abstract

Two-wave mixing (TWM) in photorefractive media is considered as a promising technique for adaptive interferometric detection cf mechanical vibrations and of laser-induced ultrasound under industrial conditions in particular [1], Because of dynamic nature of the recorded hologram, which works in this case as an “intelligent beam-splitter”, random speckle-like structure and environmentally induced general phase fluctuations in the wave-front reflected from the vibrating object are effectively compensated. Being very sensitive (limited by shot noise), the photorefractive detection configurations suffer, however, from insufficient speed of the dynamic grating formation, which, even in case of high-sensitivity semiconductor photorefractive crystals (PRCs), is limited by milliseconds.
