Optical engine for front or rear screen SLM display systems |
摘要 |
<p>An optical engine (15) for an SLM-type display system, which may be either a front or rear projection system (10, 20). The optical engine (15) provides for a high contrast, telecentric illumination angle to the SLM (33) without compromising brightness by vignetting due to offset in the pupil. The resulting offset pupil is converted to a telecentric, on-axis image by a relay path (34) between the SLM (33) and the projection lens (37). The relay path (34) places the image at an intermediate image plane accessible by a the projection lens (37), which permits the projection lens (37) to be telecentric without an offset pupil. <IMAGE></p> |
