  • Facet shape and distribution pattern for lensless imaging
    Patent number: 9413987
    Abstract: Aspects of the invention are related to a method and apparatus for capturing an image without a lens. Ambient light reflected off of objects are received through a surface of a light guide substrate and reflected off of reflective features included therein toward a plurality of photodetectors arranged on edges of the substrate. Signals generated by the photodetecotors are processed to generate images of the objects. Reflective features are arranged in such a way that a line-of-sight propagation path exists between each reflective facet and a photodetector with no or little obstruction from the other reflective features for rays of reflected light normal to edges of the light guide substrate.
