摘要:
Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Each of a set of imagers produces a portion of the final image. Relay lenses then tile the individual image portions together into a combined image. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers. The individual images are tiled together within the microprojector itself rather than on a projection screen. This allows the tiling to be adjusted once at the factory and set forever. In some embodiments, the light created for use by the microprojector is split by a polarizing beamsplitter. Each resultant polarized beam is then sent to an imager. Another polarizing beamsplitter combines the individual images.
