    摘要: An angular correction method is provided for a rotary encoder in which angular skip does not occur in determining an angle at a position of switching a combination of successive angular graduation images used in interpolation calculation. An angular correction quantity Ci includes (1) a residual ri between a position computed from a model and an actually read position P, for each angular graduation image position and (2) a tangential slope f′(xi) of residual curve, r=f(x), determined by fitting the residuals to a polynomial f(x) which is a function of angular graduation image number x. The actually-read position P is corrected as P+Ci to perform interpolation calculation determining an angle without angular skip.
