Acousto-Optic Processing of 2-D Signals Using Temporal and Spatial Integration.
Abstract
The report describes research to develop acoustooptic information processing systems capable of processing two dimensional signals. The general methodology that was developed for accomplishing this, is the use of a combination of temporal and spatial integrations in the optical system. Acoustooptic processors for synthetic aperture radar image formation were designed and experimentally demonstrated. The radar imaging processor is capable of forming images in real time with relatively low size and power requirements. Several processors were also developed for pattern recognition applications and an acoustooptic system capable of producing two dimensional correlations of images at standard video rates was experimentally demonstrated. The same signal processing method was applied to two dimensional spectrum analysis and the processing of signals from broadband adaptive phased arrays. In both instance acoustooptic architectures were developed and initial experimental demonstrations were performed.
