1. An optical logic processor employing input optical intensity to output optical spatial position mapping, comprising: an electro-optical device for receiving discrete input optical object beams each of a first or a second intensity level and for receiving a separate readout optical beam; means forming a part of said electro-optical device for producing diffracted optical outputs of portions of said readout optical beam, which optical outputs are diffracted to unique spatial positions, each as a direct function of the intensity of one of said input optical object beams or of combinations of the intensities of said input optical object beams; and means including a spatial filter having discrete apertures therein, at said unique spatial positions for transmitting selected portions of said diffracted optical outputs for implementing discrete optical logic functions.
