ABSTRACT:
At the reception site of a laser transmission system the received laser light beam is converted into a focusing cone of light. The cone of light is directed to partially illuminate the inner area of the quad photo detector array which is used to provide a highly accurate positional measurement of the laser beam. A quad photo detector is utilized to measure deviation of the laser beam from its ideal line-of-sight and provide sensing signals defining the deviation to enable its corrective adjustment. A high speed photo detector located centrally to and behind a central aperture of the quadrant photo detector permits the detection of the laser light beam voice and data.
