Abstract:
1. A laser relay module for free space optical communications comprising: an optical telescope mounted on a steerable mount for receiving and transmitting optical beams; an optical diplexer for separating transmitting and received optical beams; an optical amplifier for restoring a signal level of the received optical beam to a predetermined level for a transmitting beam; a modulated beacon laser for line of sight control of a plurality of communicating remote network nodes, and for optical transmission of status, system management, and telemetry data to other network nodes; a beacon beam detector for detecting an incoming beacon optical beam for line of sight control of the optical telescope and receiving status, system management, and telemetry data from other network nodes; and means for inserting an output of the modulated beacon laser into the optical telescope for transmission to another network node, and for collecting the incoming beacon optical beam at the optical telescope and transporting the incoming beacon optical beam to the beacon detector.
