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).
