Abstract
An optical tracking system for use in an optical receiver of an optical communication system includes a first focus unit, a tracker, and an optical fiber having an angled tip. The first focus unit receives an optical signal to be tracked and focuses it on the angled tip of the fiber. The fiber is connected to a communications detector of the optical communication system. In addition, the angled tip of the fiber reflects a portion of the focused optical signal to the tracker. The tracker processes the reflected portion of the optical signal to correct for any misalignment between the optical signal and the optical receiver.
