Tracking Retroreflective Targets On A Structure
Abstract
Optoelectronic system simultaneously measures positions of 50 retroreflective targets with 35 degree field of view, with accuracy of 0.1 mm. SHAPES, "spatial, high-accuracy, position-encoding sensor", illuminates targets with lasers in its sensor module. System repeats measurements 10 times per second and gives unambiguous indication of distance to each target. Applicable in rendezvous and docking systems, boresight determination and precise pointing of antennas.
