Some embodiments of the invention relate to a laser tracker for determining the position of a target, comprising a beam source for generating measurement radiation; a base; a beam deflection unit which can pivot with respect to the base −4° C. about two axes in a motorized manner, for the emission and alignment of the measurement radiation and to capture at least one part of the measurement radiation reflected onto the target; a first position-sensitive surface detector and an evaluation and control unit for determining a point of impact of the reflected measurement on the surface detector for generating an output signal in order to determine the position of said target. Said laser tracker also comprises a calibration device for use with a self calibrating function to determine the calibration parameters thereof with respect to a position and/or direction of the measurement radiation. |
