In a method and a system for correcting an angle-measuring and/or
distance-measuring sensor system, sinusoidal and cosinusoidal measurement
signals (x.sub.i, y.sub.i) obtained by scanning a moved object of a
measurement are evaluated. In order to correct the angle errors and/or
phase errors of the measurement signal (x.sub.i, y.sub.i) a compensation
process and a subsequent correction process are provided. Correction
parameters (m.sub.1, m.sub.2) are obtained in the compensation process,
and, in the correction process, a corrected pair of measured values
(x.sub.i', y.sub.i') is determined form each pair of measured values
(x.sub.i y.sub.i).
