Studies of the applicability of optoelectronic devices for instrumentation in high-energy physics. Progress report, June 1, 1980-May 31, 1981
W. Cleland, J. Thompson · 1981
Instrumentation research to study the applicability of optoelectronic devices to problems in High Energy Physics has been under way since June 1, 1981. The thrust of the program has been to examine possibilities for using incoherent optical processing techniques in order to carry out real-time pattern recognition on the time scale required for the triggering of High Energy Physics experiments. The properties of the various types of optical processors have been understood and an incoherent correlator which could recognize several patterns in an array of independently driven light sources, such as LEDs or injection lasers, is probably feasible. The necessary equipment and computer programs were developed to permit the production of computer-generated holograms and kinoforms, elements which would become the filters in an incoherent optical correlator. The problems of making reliable kinoforms will be studied to build a simple correlator and test its properties.
