Abstract
An optical structure includes an array of mirrors disposed on a substrate. The mirrors are disposed over a surface of the substrate and oriented at a plurality of different oblique angles relative to the surface of the substrate. The substrate comprises a clear substrate to pass external light through interstitial gaps between the mirror structures such that the optical structure is partially transparent and partially reflective. The optical structure may optionally be illuminated with an image source that emits substantially a single light ray per pixel of the image source to provide an optical system.
