Abstract: A method determines translational and/or rotational deviations between the measurement coordinate system of a measurement mirror scanner and the processing coordinate system of a processing mirror scanner. A measurement beam reflected at a workpiece returns on a path of an incident measurement beam and is captured by a spatially resolving measurement sensor to ascertain spatially resolving information of the workpiece. The reflected measurement beam, in a sensor image of the measurement sensor, is imaged onto a previously known image position. This is accomplished by ascertaining a focal position deviation of the processing beam by scanning with the processing beam, evaluating a laser power detected at grid points, fixing the processing mirror scanner, capturing spatially resolving height information of the pinhole diaphragm by the measurement sensor, and determining a translational deviation between the processing and measurement coordinate systems based on the deviation.

An aperture diaphragm, followed by a detector, is arranged at each measurement point. At each measurement point, for x-y-focal point or beam profile measurements, the laser beam is moved by the scanner optic or the x-y-movement unit in an x-y-grid over the measurement aperture in the aperture diaphragm, and, at each grid point, the laser power is measured by the detector, the scanner axis of the scanner optic or the x-y-movement unit being stationary. For z-focal point measurements, the laser beam is displaced by the focusing optic or the z-movement unit in the z direction within the measurement aperture in the aperture diaphragm.
