WU Jia-qi, YANG Dong-ying, QIAN Jin-wu. Calibration error analysis and way of calibration forspatial curvature measurement[J]. Editorial Office of Optics and Precision Engineering, 2003,(2): 166-170DOI:
The causes for spatial curvature measurement errors are analysed
and the relationship between the curvature in the direction of calibration and the signal in the direction of measurement is discussed. With a relevant formula established
a new method is proposed for the correction of the calibration error. The geometric meaning of this method is then defined not only for measurement of spatial curvature
but also for inspection for some other spatial vectors.
