    摘要: A method for improving the reproducibility of a coordinate measuring machine and its accuracy is disclosed. Using at least one measuring field of a camera, a plurality of images of at least one structure on the substrate are recorded. The substrate is placed on a measuring stage traversable in the X coordinate direction and the Y coordinate direction, the position of which is determined during imaging using a displacement measuring system. The measuring field is displaced by the amount of the deviation determined.

    摘要: A method for reproducibly determining object characteristics is disclosed. Herein an object is imaged onto a detector by means of an imaging optics and detected thereon. A correction function k is applied to a brightness measuring result N originally detected by a detector in such a way, that a corrected brightness measuring result N′ is proportional to a brightness I impinging on the detector.

    摘要: A method for correcting an error of the imaging system of a coordinate measuring machine is disclosed. The position of at least two different edges of at least one structure on a substrate is measured. The substrate may be automatically rotated into another orientation. Then the position of the at least two different edges of the at least one structure is measured on the rotated substrate. Based on the measurement data, a systematic error of the imaging system is eliminated.
