Abstract
In a method and a system for correcting an angle-measuring and/or distance-measuring sensor system, sinusoidal and cosinusoidal measurement signals (x, y) 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, y) a compensation process and a subsequent correction process are provided. Correction parameters (m, m) are obtained in the compensation process, and, in the correction process, a corrected pair of measured values (x, y) is determined form each pair of measured values (xy).
