Abstract
An optical atmospheric link device which is adapted to quickly correct the incident position of a light beam with high follow-up accuracy. Incident position detection signals are generated by an optical beam incident position detector in correspondence to the incident position of a first optical beam. The incident position detection signal along with a reference incidence position signal, are utilized to generate incident position correcting signal. The incident position correcting is utilized to move a lens to quickly correct the incident position in a small amplitude mode. Furthermore, a displacement detection signal is generated which corresponds to the displacement of the lens. The displacement detection signal and the incident position correcting signal are utilized to move a pair of mirrors to slowly correct the incident position in a large amplitude mode.
