Abstract
The video-frequency space-integrating acousto-optic correlator (SIAOC) extending the functional possibilities of the correlating type acousto-optic processors (AOP) is discussed. The architecture is realized on the basis of the acousto-optic matched filter with two- dimensional reference mask. It enables us to perform the filtering and forming of the arbitrary video-signals with the spectrum width limiting by the acousto-optic modulator (AOM) bandwidth only. Theoretical analysis of the novel scheme showed it to be equivalent to the video-frequency linear electric filter, its pulse response being fully determined by the reference mask structure. A procedure for the latter synthesis from given analog bipolar function is considered. The experimental results are presented.
