Abstract
An embodiment of the invention includes using a set of telescopes to calibrate a three dimensional optical scanner. Three separate calibrations are disclosed for a survey grade calibration: () angular calibration, implemented using at least one anti-podal pair of telescopes, () range calibration, implemented using at least one telescope mounted fiber recirculator, and () tilt calibration, implemented using at least one pair of telescopes not mounted in anti-podal configuration and an integral tilt table. Methods for aligning or measuring the mis-alignment between anti-podal telescope pairs are also described.
