Method and arrangement for correcting an angle-measuring and/or distance measuring sensor system

摘要

Disclosed are a method and a system for correcting an angle-measuring and/or distance-measuring sensor system ( 1 ), in which sinusoidal and cosinusoidal measurement signals (x_i, y_i) obtained by scanning a moved object of measurement ( 2 ) are evaluated. In order to correct the angle errors and/or phase errors of the measurement signals (x_i, y_i), the method includes a compensation process and a subsequent correction process. Correction parameters (m₁, m₂) are obtained in the compensation process, and, in the correction process, a corrected pair of measured values (x_i', y_i') is determined from each pair of measured values (x_i, y_i).
