  • Patent number: 7961395
    Abstract: Systems and methods are provided for providing wideband diffraction limited performance in an optical receiver. A first lens is constructed from a first material and has a first surface and a second surface. A second lens is constructed from a second material and having a first surface and a second surface. The second lens is positioned such that a first surface of the second lens faces a second surface of the first lens across a gap of air. A diffraction grating is applied to one of the first and second surfaces of the first and second lenses.
    Type: Grant
    Filed: July 17, 2007
    Date of Patent: June 14, 2011
    Assignee: Northrop Grumman Systems Corporation

  • Patent number: 6834970
    Abstract: An apparatus in one example comprises a corner cube that comprises a first side, a second side, and a third side that cooperate to retro-reflect an incoming beam of light and output an outgoing beam of light. One or more of the first side, the second side, and the third side of the corner cube serve to contribute substantially to a decrease of over twenty percent in an amplitude of the outgoing beam of light relative to an amplitude of the incoming beam of light.
