Abstract:
1. An optical system capable of a panoramic field of view, comprising: a telecentric eyepiece; a microlens array with anamorphic lenslets, wherein a focal length in a horizontal axis is made different from a focal length in a vertical axis; and a microdisplay capable of displaying a panoramic field of view, wherein said microdisplay is modified by removing a color filter from its pixels and subpixels for monochromatic imaging, and driving the resulting subpixels as monochromatic pixels to produce an aspect ratio up to 1:3, said microlens array being aligned such that each anamorphic lenslet is disposed in correspondence with a respective monochromatic pixel, and wherein horizontal and vertical axes of the pixels have equal instantaneous fields of view, whereby rectangular pixels are made to appear square.
