Abstract
Some embodiments of the invention relate to a laser tracker for determining the position of a target and in particularly for the continuous tracking of the target. In some embodiments, the laser tracker includes a beam source for generating measurement radiation, an angle measuring function for determining a horizontal pivot angle and a vertical pivot angle, a distance measuring function and a position sensitive surface detector for determining a point of impact of the reflected measurement radiation on the surface detector and for generating an output signal in order to control a target tracking function. The laser tracker may include a self-calibrating function for calibrating a beam offset using a reflecting calibration device.
