Abstract

Bulk acoustooptic devices operating in the Bragg and Raman-Nath modes represent commercially available real-time transducers capable of spatially modulating coherent light proportional to an input electrical signal Although these devices are 1-D, new architectures and algorithms enable them to realize many 2-D signal-processing functions such as spectrum analysis, correlation, and range-Doppler processing. We briefly review the basic architectures and algorithms for these systems, and we then describe new advanced signal-processing concepts utilizing these devices with particular attention to matrix-vector, iterative, and systolic array signal processors.
