초록

A system and method are provided using a photodetector array for producing an output signal which is compensated for the effects of ambient light, photodetector bias, and the like, wherein the output signal contains information indicative of the position of the object. The preferred embodiment is useful for vehicular wheel alignment and includes left and right wheel units for coupling to respective left and right steerable wheels of a vehicle, and a central microcomputer and CRT display operably coupled with each wheel unit. Each preferred wheel unit inc...
