Abstract

Laser beam's acquisition, pointing and tracking are crucial technologies of free space optical communication. Fine tracking system is an important component of APT (acquisition, pointing and tracking) system. Traditional fine tracking system use CCD or quadrant detector as the position detector of signal light. In order to simplify the system and improve accuracy, we propose a fine tracking system based on fiber nutation which don’t need a position detector and theoretically prove that the system is feasible. Meanwhile corresponding fine track system was built, experiment on position detection of the fine tracking system is done.
