Direct view deformable mirror device
First Claim
1. A method of directly viewing an image generated by a digital micromirror device (DMD) having mirror elements that tilt to an on tilt angle, comprising the steps of:
- forming both ends of a number of optical fibers at a bias angle that is determined by said on tilt angle;
grouping said optical fibers into a faceplate having a planar bottom surface and a planar top surface defined by said ends;
placing said bottom surface parallel to and near the reflective surface of said DMD; and
viewing an image generated by said DMD at said top surface.

Abstract
A faceplate (10a) for directly viewing an image generated by a digital micromirror device (10b), which generates images by tilting tiny mirror elements (11) to on or off positions. The faceplate (10a) has a number of optical fibers (12) parallel to each other and closely spaced together. The ends of the optical fibers (12) are the top and bottom surfaces of the faceplate (10a). Both ends of each fiber (12) is sliced at an angle determined by the on position of the mirror elements (11). This permits light to travel down the fibers (12) and be reflected back to the viewer by only those mirror elements (11) that are on.

9. A direct view display system, comprising:
-
a digital micromirror device for generating images by tilting an array of mirrors to on or off tilt angles; an image data processing system for generating image data representing said image and for delivering said data to said digital micromirror device; and a faceplate having a number of optical fibers, attached together such that they are parallel to each other and closely spaced, wherein said fibers are of equal length so as to provide a planar shape of said faceplate, and wherein the end surfaces of said fibers comprise an upper and a lower surface of said faceplate, and wherein said optical fibers have a bias angle with respect to the plane of said faceplate that is determined by said tilt angle of said mirror elements. - View Dependent Claims (10, 11, 12)
