SHE Lin, FENG Chang-you, DING Lin-hui. Measurement of encoder errors with two-step method[J]. Editorial Office of Optics and Precision Engineering, 2004,(1): 66-70DOI:
The encoder errors obtained by measuring the encoder errors with an encoder angular testing system consisting of polyhedrons and an autocollimator
include encoder errors and calibration errors of polyhedrons. According to the conditions for use of two-step method
the two-step method is applied to the processing of photoelectric rotary encoder errors
and the calibration errors of polyhedrons and the encoder errors are separately obtained. The results of error separation are close to the results obtained by other methods
but the volume of data to be measured for use of two-step method is dramatically reduced. The results of comparison show that
in comparison with other methods
this method can be used to improve the measurement efficiency by more than 90%
and shorten the measurement time by nearly 80%.
