Abstract

We report on a technique for implementing general filtering operations in acoustooptic signal processing systems. We use a binary recording method called area modulation to reduce linearity problems associated with spatial light modulators that operate by controlling the amplitude of light. We present an analysis of this method, we report on experiments with an acoustooptic system to verify the analysis, using photographic film and a liquid crystal display to implement the area modulation masks, and we discuss the limitations of the technique.
