An improved laser scanning apparatus ( ) for determining frame or unibody alignment or misalignment of a vehicle ( ) is provided, which includes a laser assembly ( ), a pair of rotatable mirror assemblies ( ) and laser detectors ( ) located within an enclosed housing ( ). The laser assembly ( ) has an upper pair of lasers ( ) located in known, spaced relationship above a lower pair of lasers ( ); detector assemblies ( ) are also provided including substantially parabolic reflective surfaces ( ) with detectors ( ) disposed substantially at the focal point of the surfaces ( ). The apparatus ( ) is used in conjunction with a plurality of individually coded reflective targets ( ) which are suspended from known reference points on the vehicle ( ). In use, the laser assembly ( ) in conjunction with the mirror assemblies ( ) directs upper and lower laser beams through 360 degree scans to impinge on the targets ( ); laser radiation reflected from the targets ( ) is detected by the detector assemblies ( ), allowing trigonometric calculation of target positions using information derived from the scans of the upper and lower beams. In this way, a determination can be made if any of the targets ( ) are out of plumb (i. e.
