Abstract

Relay mirror is used to track ground-based beacon accurately in space optical communication. It is unreliable to track the beam by the ordinary quadrant. DBA video tracker applies avalanche photo diode quadrant to enhance, which can improve the performance of the relay mirror tracking system. However, the sight line disturbance followed is unacceptable. By the continuous designs we present the scheme of enhanced video tracker with high-passed high bandwidth quadrant, and it is proved that it is successful for the relay mirror experiment.
