Abstract: An apparatus and method for compensating a coordinate measurement machine is provided, which may be 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 R0 parameters by means of embedded temperature sensors.

Abstract: A scale-bar artifact is and measurement method is provided, the artifact comprising a shaft, at least one mounting nest positioned on the shaft, a plurality of target nests positioned on the shaft, at least one temperature sensor in contact with the material of the shaft and a computer or circuit board in communication with the at least one temperature sensor, wherein the computer or circuit board is configured to receive temperature sensor data and to compile temperature corrected distance measurements corresponding to at least one linear portion of the shaft. Additionally, a scale-bar artifact is provided, comprising a shaft, a plurality of target nests positioned on the shaft and at least one mounting nest positioned on the shaft, wherein the at least one mounting nest comprises either at least one adjustable kinematic mounting nest or at least one fixed kinematic mounting nest configured to receive a separate mounting component.
