| 摘要 |
The invention relates to a method for determining at least one influencin g variable acting on the eccentricity in a goniometer, using a detector arra ngement consisting of four optical detector elements (3), and a rotational b ody comprising a plurality of pattern elements (6) arranged around a pattern centre (MZ), the rotational body being rotatably arranged about an axis (4) . According to said method, at least some of the pattern elements (6) are re produced on the detector arrangement, the positions of the pattern elements (6) reproduced on the detector arrangement are resolved, and the eccentricit y of the pattern centre (MZ) in relation to a detector centre (DZ) of the de tector arrangement is determined. A plurality of such eccentricity measureme nts for different rotational positions enables different influencing variabl es acting on the current eccentricity to be separated, especially by forming units.
