Infrared Liquid Crystal Light Valve

An advanced dynamic infrared (IR) image projection system based on liquid crystal light valve (LCLV) technology is described. The IR-LCLV is capable of presenting a complex IR dynamic image with high spatial and temperature resolution and wide dynamic range at video frame rates. Experimental results obtained from an IR-LCLV utilizing a cathode ray tube as the input source and an extended IR source (blackbody) as the projection beam are presented.
