Method and system for optically tracking a target using a triangulation technique
Abstract
An optical position-tracking system (200) comprises a first light beam steering device for sweeping a first light beam (224) through a first angular range (230) to cause a reflection (225) of the first light beam (224) by a target (205). Additionally, the optical position-tracking system (200) further comprises a second light beam steering device for sweeping a second light beam (222) through a second angular range (232) to cause a reflection (223) of the second light beam (222) by the target (205). Moreover, the optical position-tracking system (200) enables determination of a position of the target (205) using a triangulation technique utilizing a first angular value of the first light beam (224) and a second angular value of the second light beam (222). The first angular value and the second angular value depend on the existence of the respective reflection.
