Abstract
A system and method in the field of free space optical communications (FSOC) for overcoming atmospheric-induced spatial optical signal variations operates within each of two FSOC terminals that make up a bi-directional FSOC link, with each terminal providing the rapid adaptive beam path method over a much wider field of view than typically used for adaptive optical techniques. Each terminal uses a real-time adaptive beam-steering technique that continuously measures optical power and optical power gradients by the receiver optical detectors; this data is sent to a control system that automatically responds by re-aligning the optical system accordingly by maximizing the optical signal power measured by the optical power receiving detector.
