IMAGER TO IMAGER RELAY LENS SYSTEM

摘要

A lens system for use in a two-stage projection system that relays light output from a first imager on a pixel-by pixel basis onto a second imager (e.g.an LCOS). The lens system includes a double gauss lens set having a distortion of less than about 0.015% with at least about 90% of the light energy of a specific pixel projected within about a 15.4 micrometer square. Thus a projection system that enhances the contrast ratio for video images, particularly in the dark state, and reduces contouring artifacts, can be achieved.
