Abstract

Briefly, in accordance with one or more embodiments, a compressed microlens array comprises an array of lenslets arranged in the array to have the lenslet centers spaced apart at a first distance in a first direction and to have the lenslet centers spaced apart at a second distance in a second direction such that the first direction is greater than the second direction. A raster scan of an image projected onto the array of lenslets results in the image being displayed in an eyebox having an aspect ratio having a length in the first direction being longer than a length in second direction via virtual vignetting of the diffraction patterns resulting from the raster scan.
