  • Internal reflection apparatus and method using a holographic optical element for a free space optical communication system
    Patent number: 6724508
    Abstract: An apparatus for a free space optical communication system includes an element having a front surface and a back surface. A holographic optical element (HOE) is disposed to receive a light signal from the free space optical communication system, and to angularly direct the light signal, having a certain wavelength, towards one of the surfaces of the element to allow the light signal to propagate between the front and back surfaces of the element via total internal reflection. The internally reflected light signal eventually converges and is received at an optical detector circuit. At the same time, light having other wavelengths, including visible background light, passes through the HOE, thereby giving the apparatus an appearance of being transparent and unobtrusive.

  • Window-mounted free-space optical wireless communication system
    Publication number: 20020109886
    Abstract: A compact, lightweight free-space optical communication system is mounted to a window, such as to a surface of the window. Mounting can be accomplished using glue, vacuum devices, or other fastener devices or fixtures. The optical communication system has features that compensate for window dynamics and other window characteristics, including fast steering solutions for pointing and tracking, and terminal size and weight factors.
