DYNAMIC OPTICAL SIGNAL TRACKING ON A DETECTOR ARRAY IN A FREE SPACE OPTICAL COMMUNICATION SYSTEM

摘要

A free-space optical communication system includes a detector array(102; 202) having a plurality of detector elements (204) and a transmitting source(210; 310). Dynamic movement of the optical signal on the detector array is caused by changes in orientation of the transmitting source. A tracker (206) 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.
