ABSTRACT:
A vehicle wheel alignment measurement system includes four infra-red emitter-detector units fixed by clamps to the vehicle wheels. Each unit includes a beacon and a rotatable detector coaxial with the beacon and driven by a motor. Angular rotation of the detector is sensed and signals from the four units are analyzed by a signal processing computer to give absolute position and relative angular measurements of the four wheels.
