- PROJECTION DISPLAY HAVING MULTI-CHANNEL OPTICAL SYSTEM HAVING NON-CIRCULAR OVERALL APERTURE

摘要

There is provided an imager 30 that is implemented to generate development images within the distribution of sub-areas 33-1 through 33-7 of the image plane of the imager 30 in the projection display. The projection display also includes one assigned sub-region 33-1 through 33-7 of the imager per each of the channels 44-1 through 44-7, such that the mappings of the individual images are coupled to the entire image within the projection region Channel optical device 40 that is configured to map a plurality of channels. At least some of the channels of the multi-channel optic device 40 are disposed along at least one curve similar to at least one elongated image feature of the entire image 5, and thus each two-dimensional anisotropic defocusing aspect of the projected image point Is obtained. In this way, the depth range of the large focal spot can be combined with the relatively large projection brightness without loss of the focused view of the image feature being projected with sufficient focal point.;
