Abstract
A possibility of a new class of optoelectronic image correlator design on the base of the novel light controlled photodetector is discussed. The light controlled photodetector was proposed earlier. The correlator operates in quasi-real time, i.e. with the speed of the input images to be processed. The distinguished feature of the correlator is the parallel calculation of the two-dimensional mutual correlation function of the analyzed image directly in the structure of the light controlled photodetector. Owing to this, the high operation speed is provided. Experimental results confirming the possibility of proposed image correlator realization are presented. The possibility of designing the correlator with image input on the base of LC SLM with electronic addressing and on the base of light emission diode matrix is proposed. In the latter case the correlator can be realized as a chip. The proposed correlator can be used in the intelligence systems of technical vision.
