Abstract (en)
[origin: WO2005124286A1] Disclosed are a method and an arrangement for correcting an angle-measuring and/or distance-measuring sensor system (1), in which sinusoidal or cosinusoidal test signals (xi, yi) obtained by scanning a moved test object (2) are evaluated. In order to correct the angle errors and/or phase errors of the test signals (xi, yi), the inventive method comprises a balancing process and a subsequent correction process. Correction parameters (m1, m2) are provided in the balancing process while a pair of corrected measured values (xi, yi) are determined from each pair of measured values (xi, yi) in the correction process.
