Title: MULTI-POINT FREE SPACE OPTICAL COMMUNICATION SYSTEM
Abstract:
A system includes an optical transceiver (204, 204a) configured to transmit/receive at least one optical feed (220) and a beam separator (210) configured to separate the optical feed into a plurality of optical beams (20, 20a-f), and spatially combine the optical beams into the optical beam. The system also includes a dichroic mirror (212) optically coupled to the beam separator and configured to reflect the optical beams, and allow beacon signals (224, 224a-f) to pass therethrough. A position sensitive detector (228) of the system optically couples to the dichroic mirror and is configured to sense an incidence position of each beacon signal allowed to pass through the dichroic mirror, and output a position error (230) for each optical beam based on the sensed incidence positions.
