Display Characteristics of Example Light-Valve Projectors

Abstract

This report provides quantitative data on performance characteristics of light valve projectors in simulator displays as well as in optimal laboratory conditions. Two types of light valve projectors are discussed: a single light- valve projector (also called Talaria) and a multiple light-valve projector. The data show that (a) these projectors do not achieve brightnesses above the mesopic level in large-screen simulator displays, (b) color output includes a 'dark-field haze' which must be dealt with like ambient illumination, and (c) light/dark ratios (L/D) above 5:1 are obtainable only when the light region is white or yellow-green. Keywords: Chromaticity; Contrast; Display systems; Flight simulation; Light modulators; Light-valve projector; Luminance; Mesopic vision; Modulation transfer function; Resolution; Optical properties.
