Abstract

We present and characterize theoretically and experimentally a photorefractive velocimeter. This device, based on two-wave mixing in a rapid photorefractive crystal, measures the instantaneous velocity of a vibrating target. It is particularly adapted to the measurement of high-amplitude (up to several mm) low-frequency (up to several kHz) vibrations. Instantaneous velocities as high as 25 mm s-1 are expected to be measured with common photorefractive semiconductors and CW lasers
