Abstract

Two new applications of the photorefractive phenomenon to optical velocimetry are described. One of them concerns the laser Doppler velocimetry with photorefractive two-wave mixing. The second application is covered by the particle image velocimetry, where a photorefractive crystal volume and a set of light sheets are used, respectively, for sampling the flow field in depth instantaneously and for illuminating the fluid volume sealed by small particles.
