Abstract

The use of photorefractive crystals as optically addressed time integrating spatial light modulators is discussed. Photorefractive crystals can be used to implement variable filters in acoustooptic systems, and in particular, applica-tions in signal detection and adaptive signal processing are discussed. The bias-free time integrating property of the crystals is demonstrated.
