Abstract: 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.

Abstract: The present invention provides a method for photographing lustrous objects, including even spectacle frames with highly reflective surfaces such as metal frames, that enables the objects to be photographed more naturally and aesthetically without any reflection on the surface of the camera or lens.
