<p>The laser tracker has a base that is provided with a calibration unit (60) with a first retro-reflective reference target (70) and an optical lens assembly (50). The calibration unit is used to determine a calibration parameter with a measurement radiation (55) such that beam path through the optical assembly is extended, and the measurement radiation to reference target is reached. A first calibration measurement with a simulated distance to the reference target is feasible, and the simulated distance is greater than distance (d') to the reference target. Independent claims are included for the following: (1) a calibration method for determining calibration parameter for laser tracker; and (2) a computer program product storing program for performing method for determining calibration parameter for laser tracker.</p> |
