Systems and methods for weighted combination of quadrant photodetector output for beam tracking

The disclosed system may include (1) an optical element that receives an optical beam, (2) a wide field-of-view (FOV) quadrant photodetector that receives, from the optical element, first light originating from the optical beam, (3) a narrow FOV quadrant photodetector that receives, from the optical...

Zusammenfassung:The disclosed system may include (1) an optical element that receives an optical beam, (2) a wide field-of-view (FOV) quadrant photodetector that receives, from the optical element, first light originating from the optical beam, (3) a narrow FOV quadrant photodetector that receives, from the optical element, second light originating from the optical beam, and (4) a controller that controls an orientation of the optical element during at least a period of time based on a weighted combination of (a) output of the wide FOV quadrant photodetector in response to the first light, and (b) output of the narrow FOV quadrant photodetector in response to the second light. Various other systems, methods, and computer-readable media are also disclosed.
