Paper Abstract
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.
