1 August 1990 Full-color, liquid-crystal light-valve projector for shipboard use
Author Affiliations +
A full-color projection display system, using CRT driven Liquid Crystal Light Valves (LCLV5), is specifically designed to withstand the rigorous environmental requirements of surface ship applications. The projection system is designed to allow the Navy to upgrade its current monochromatic displays to full-color capability. The projector contains three optical subsystems: the arc-lamp housing, the fluid-filled prism, and the relay projection lens. Illumination is provided by a 750-watt xenon arc lamp that is prealigned and prefocused inside a replaceable module. The fluid-filled prism polarizes the arc-lamp light and separates it into the red, green, and blue primary colors. The projector contains three LCLV5 (one for each primary color). Images are reflected off the light valves and relayed back though the prism to a single projection lens. The wide-angle projection lens directs the image to a 42-inch square projection screen. Image registration is achieved by both dynamic digital--orrection circuitry and by screen sensors that provide feedback to the projector's analog deflection drivers.
