Abstract
Systems and methods for testing or correcting optical pointing systems are disclosed. An optical pointing system may include an imaging sensor including a field-of-view (FOV) carried by the optical pointing system, at least one collecting device for collecting optical photons and directing the optical photons to the imaging sensor, at least one directing device for directing the at least one collecting device to different pointing vectors, and at least one non-transitory computer-readable storage medium carried by the optical pointing system having instructions encoded thereon that when executed by at least one processor operates to test the optical pointing system by, inter alia, determining a pointing error based, at least in part, on a macro image of a targeted object.
