Abstract : The objectives of the program were: (1) to improve the characteristics of the low resolution (40 lines/inch) photoconductive-electroluminescent (PC-EL) type image intensifier panel; (2) to construct a high resolution (1000 lines/inch) PC-EL type image intensifier; (3) to build an experimental model compact optical projection system, incorporating the image intensifier panel. Panels with the best uniformity, least graininess and widest half-tone range reproducing capability had maximum standard luminous gains (measured with a 2870K tungsten light source) of 20 foot-Lambert per foot-candle and maximum output brightnesses of 30 foot-Lamberts at 200 volts and 2000 cps. Response times between 50 and 500 mseconds were measured. Work is being continued toward improving the speed, spectral response, gain, and life characteristics of PC layers, developing the high resolution image intensifier panel, and building a compact optical projection system with the improved image intensifier panels.
