Abstract: Laser scanners are used for determining deformation in vehicle bodies and the like, using a laser scanning apparatus in conjunction with a plurality of coded targets suspended from (or in known relationship to) known reference points on the vehicle to calculate three dimensional spatial coordinates defining the actual positions of the targets, and to compare such calculated positions with manufacturer-provided specification values. The present invention provides improved signal collection through the use of an independent synchronization circuit that uses a fiber optic cable for signal collection; improved component isolation through the use of a mounting plate and isolation mounts; improved component alignment through the use of easier and more reliable alignment mechanisms; and improved data collection and processing through the use of onboard data averaging and filtering.
