Abstract

Studies completed during the past two years at the Operations Training Division of Air Force Human Resources Laboratory (AFHRL/OT), Williams AFB, provide comparative data on a single light-valve projector (SLVP) using one xenon arc source and a multiple light-valve projector (MLVP) using two sources and two light valves with common final optics. Spectral energy distributions (SEDs) of light-valve primaries are continuous distributions without the spikes characteristic of some CRT phosphor emissions. Equations relating digital RGB codes to color output must take into account an unavoidable "dark field haze" resulting from the internal optics of these projectors. This "haze" can be considered as a constant additive factor analogous to ambient illumination on a cathode-ray tube.
