Multiple exposure holographic interferometry with sillenite crystals applied to vibration measurement

A holographic camera is presented, which uses a sillenite crystal as dynamic recording medium. The camera operates in a pulse regime and is used to provide vibration analysis of an object. A 4 pulse real-time holographic technique was implemented to measure the amplitude and phase of the vibration. The implementation of this technique required bringing under control a Q-switched YAG laser. We present the experimental results for a metallic plate driven by a vibrating loud speaker.
