ABSTRACT:
A free space optical communication system includes an adaptive optical power regulator. The adaptive optical power regulator adapts to changes in effective loss associated with the free space optical path. In one embodiment the adaptive optical power regulator adapts to scintillation losses. In another embodiment, the adaptive optical power regulator further adapts to changes in atmospheric loss associated with changes in weather.
