<P>PROBLEM TO BE SOLVED: To provide a projection system that enhances a contrast ratio for video images, particularly in the dark state, and reduces the contouring of an artifact. <P>SOLUTION: A lens system is for use in a two-stage projection system that relays light outputted from a first imager 50 on a pixel-by pixel basis to a second imager 60. The lens system includes a double gauss lens set having distortion smaller than about 0.015% with at least about 90% of the light energy of a specific pixel projected substantially within a 15.4 micrometer square. <P>COPYRIGHT: (C)2011,JPO&INPIT |
