Imaging system
First Claim
1. An optical system for a light valve, comprising:
- (a) a source of light;
(b) a lens system, said lens system directing a beam of light from said source onto a light valve;
(c) said light valve reflecting said beam, with the portion of said reflected beam unmodulated by said light valve forming an image of said source plus diffraction orders at a first region in a plane and with the portion of said reflected beam modulated by said light valve forming an image of said source at a second region in said plane, said first and second regions disjoint; and
(d) an imaging system located at said plane, said imaging system imaging said light valve onto a receptor with said reflected beam.

Abstract
Optical systems for imaging activated pixels of a linear cantilever beam light valve (14) on a receptor or screen (24) are disclosed. The systems include a light source (12), a condenser lens (16) and pupil mask (26) forming a beam (32) from the output of the light source (12), a relay lens (18) for the beam (32) to image the pupil mask (26) onto the linear cantilever beam light valve (14), and an imaging lens (22) with an optional iris diaphragm (50) for imaging the portion of the beam (32) reflected from activated pixels of the light valve (14) onto the receptor or screen (24) while blocking the portion of the beam (32) reflected or diffracted from the remainder of the light valve (14).
