Abstract :
Summary form only given. We present a novel technique for recording and processing the speckle from a displaced object. We use an optically addressed, multiple-quantum-well spatial light modulator (MQW-OASLM). This device offers high resolution, speed, and sensitivity. It allows us to measure dynamic speckle patterns at rates up to tens of kHz.
