IMAGE PROJECTOR WITH MULTIPLE IMAGERS

Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Light created for use by the microprojector is split by a polarization-sensitive element into a number of beams. Each polarized beam is then sent to an imager. Each imager modulates the light beam to produce a portion of the final image. Another polarization-sensitive element directs the individual image portions through a projection lens system so that when they are projected, the individual image portions tile together into a seamless projected image. This technique uses essentially all of the original light, doubling the lighting efficiency of previous devices. 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.

IMAGE PROJECTOR WITH INTERNALLY TILED INTERMEDIATE IMAGES

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.
