  • Dynamic optical signal tracking on a detector array in a free space optical communication system
    Publication number: 20090110406
    Abstract: A free-space optical communication system includes a detector array having a plurality of detector elements and a transmitting source. Dynamic movement of the optical signal on the detector array is caused by changes in orientation of the transmitting source. A tracker tracks the movement of the optical signal in real-time on the detector array. An output signal is derived from at least one of the detector elements illuminated by the optical signal.
