  • Rapid acquisition, pointing and tracking optical system for free space optical communications
    Patent number: 8160452
    Abstract: An acquisition, pointing and tracking system for free space optical communications systems performs the pointing and tracking function internally by way of translating an internal optical fiber in the focal plane of the transceiver telescope with a reflecting mirror in the telescope focal plane of each linked transceiver. The beam reflected from the mirror records the exact direction of the reflected beam at the transmitting beam's transceiver terminal, providing the transmitting source to lock on to the receiving telescope, allowing for the link to be acquired.
