Abstract
A fully-passive optical system creates a counter-propagating reference beam, which may be used to evaluate a misalignment between a receive beam, a transmit beam, and a tracking beam. The system can be mated to a motorized tip-tilt stage, and can measure power of received signals and automatically adjust the tip-tilt stage in response. Thus, the system would always maintain bore-sight with the received beam regardless of mechanical shift over time.
