Abstract

A multi channel video engine (10) for accepting, dividing, modifying and recombining light to project an image. A housing (12) encloses an optical assembly (28) having a dichroic mirror assembly (58) and a color cube (60). A plurality of LCD assemblies accept light from the dichroic mirror assembly (58), modifies it, and reflects it to the color cube (60). A lens assembly (16) is affixed to a bulkhead (24) of the housing (12) using a lens cradle (14) and lens retainer (18). An output prism (54) aligns light onto a second plane (70) to coincide with an optical axis (72) of the lens assembly (16).

Description

technical field [0001] The present invention relates to multi-channel imaging devices, and more particularly to projection-type imaging devices, where it is very important to precisely align the actual components of the device so that the individual components of a resulting image The color components will be tuned. The present primary application of the multi-channel imager of the present invention is as a component of a projection video display device where it is desirable to have a robust and precisely aligned opto-electronic arrangement for projecting well aligned color image. Background technique [0002] A typical configuration for a multi-channel imaging system will have a clamshell configuration where the internal optics and components are assembled from above and the optical cavity is split in half along a horizontal plane. However, the construction of such a device results in two or more planes of assembly. For example, at least one is horizontal for housing sep...
