US Patent 10382700 Optical multiplexing and overlaid subpixel processing

An imaging system. In some embodiments, the system includes an image multiplexer, an imaging lens, a coded mask, an array detector comprising an array of pixels, and a processing circuit. The imaging lens and the image multiplexer are configured to superimpose a plurality of fields of view onto the array detector. The image multiplexer is controllable to shift each field of view by a respective image offset, and the coded mask is controllable to shade each of the pixels with a respective individual mask pattern.
