Abstract
Application of acousto-optical cells in optoelectronic systems for signal processing allows to realize a high-speed data input and to provide the real-time signal optical processing. The nature of acousto-optical cells permits to realize the processing of only one dimensional data massive. But principal possibility of hybrid optoelectronic systems creating for two dimensional data massives processing exists. We propose to utilize the optical astigmatic element in an acousto-optic device for obtaining the simultaneous time delay and frequency multichannel processing. For this purpose we create the acousto-optic device for spatial data processing on the base of acousto-optic cells in the combination with matrix-array photodetector and special phase shift optical element. Investigation of the acousto-optic device characteristics is carried out.
