| Abstract: | This paper takes T3 laser tracker of API as an example to analyze measurement accuracy of laser tracker by experiments including contrast measurement before and after instrument calibration, repeated measurement of fixed point, contrast measurement with interferometer, mean square error of a point, and contrasts laser tracker measurement with the conventional measurement method. The results indicates: for laser tracker short range measurements, distance measuring error plays a leading role in measurement accuracy and gets worse as distance increases, but angular accuracy is stable. The measurement accuracy of laser tracker is higher than the conventional measurement method. |
| Keywords: | laser tracker accuracy mean square error of a point repeated measure contrast measurement |
