SELF-COMPENSATING LASER TRACKER

摘要

An apparatus and method for compensating a coordinate measurement machine is provided, which may be, e.g. a laser-based coordinate measurement machine, laser tracker, or other coordinate measurement device. In one exemplary method, such compensation comprises self-compensation of payload parameters by means of embedded tracker targets. In another exemplary embodiment, such compensation comprises self­ compensation of payload, azimuth-post, axis, or RO parameters by means of embedded temperature sensors.
