We report here the feasibility of coupling an image intensifier tube directly with the ac liquid crystal light valve, which is briefly described and characterized in the paper, to form a compact, real-time, incoherent-to-coherent image converter. This hybrid device is capable of sensing image intensity levels of less than 10-6 In addition, the same combination can be used as an image amplifier with an intensity gain of up to 10. In the experiments performed we mated an 18 mm aperture micro… Expand
Design considerations for an active feedback optical system
The optical processor proposed here consists basically of a coherent light source and two liquid crystal light valves, of which the first converts incoherent input patterns into coherent ones; theExpand
