Title:
イメージャとイメージャのリレーにおけるレンズシステム
Document Type and Number:
Japanese Patent JP2006509244
Kind Code:
A
Abstract:
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.
