Abstract
A review of photodetector arrays and architectures is presented for acousto-optical (AO) signal processing applications, for which the demands on photodetector arrays are substantially greater than for image sensing applications. The primary design considerations for obtaining photodetector arrays with high dynamic range, high sensitivity, high speed, and low crosstalk are discussed. The current status and future needs for detector arrays for AO signal processing are presented. Several novel detector structures and concepts that have potential for future AO optical signal processing use are described.
