Abstract
A dual mode laser/microwave transceiver for use in line-of-sight communications includes a housing that is formed with a single aperture for receiving both a laser beam and a microwave beam. A turning mirror and a beam splitter are mounted within the housing, and the turning mirror reflects an incoming laser/microwave beam onto the beam splitter which separates the laser beam from the microwave beam. The microwave beam is then directed by the beam splitter toward a microwave feed that is mounted on the housing. On the other hand, the laser beam is directed by the beam splitter toward an optical receiver that is mounted on the housing. Transmitted laser and microwave beams are respectively sent through the transceiver in directions opposite to that of the received beams.
