Abstract

We present a new holographic vibrometer based on dynamic holograms written in a GaAs crystal. It measures the instantaneous velocity of a vibrating target even with a rough surface. It is adapted to the measurement of high amplitude (as high as some mm) low frequency (until some 10 kHz) vibrations.
