Abstract:
1. An optical structure, comprising: a substrate having a surface; and an array of mirror structures disposed on the substrate, wherein reflective surfaces of the mirror structures are oriented at a plurality of different oblique angles relative to the surface of the substrate, wherein 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, wherein at least a portion of the mirror structures have their reflective surfaces obliquely angled relative to the surface of the substrate in two axes of rotation, wherein the different oblique angles of the mirror structures have fixed positions that are configured to reflect rays of light emanating with a plurality of divergent angles from a single source point positioned in front of the optical structure to a single destination point also positioned in front of the optical structure.
