OPTICAL MEASURING PROBE CALIBRATION

摘要

The invention relates to a calibration device (1) and to a coordinate measuring system for measuring the signal-inducing sensing deflection ITr of tactile measuring probes (2). A reference surface (8) of the reference element (7) is arranged with respect to the field of view (9) of the detector (5) in such a way that, in the event of signal-inducing contact of the sensing surface (4) of the sensing element (3) with the reference surface (8), the sensing surface (4) or parts of the sensing surface (4) lies or lie in the field of view (9) of the detector (5), the detector (5) and the calculation unit (6) being able to calculate the precise position of the sensing element (3) from the detected part of the sensing surface (4).
