Paper Abstract

Projection lenses are often designed without due consideration to the illumination system. Likewise, most illumination systems are designed to produce a specified intensity and distribution at the LCD surface, without full consideration of the projection optics, and their potential impact to the uniformity at the projection screen. In addition, the effect of the illumination system on the actual MTF of a projection lens can be dramatic (both favorably and unfavorably) compared to the standard MTF calculation which assumes uniformly filling the entrance pupil of the lens. These and other matching issues are discussed, along with ways to analyze and design a well matched system.
