    • A sensor method and apparatus for an optical wheel alignment machine utilizes one or more light sources, such as lasers (12, 13, 14), to project a laser line or other shaped light onto various locations about the sidewall (32a) of a tire undergoing measurement. The sensor includes a video camera (18) or other light responsive receiver and an optical system (16) that combines the reflected laser lines into a single image that is received by the camera. The optical system also rotates one or more of the reflected laser lines so that all of the reflected portions have the same general orientation upon entering the camera. The camera outputs a video data stream that is indicative of the image. The sensor has an electronic circuit (20) that compares the incoming video data stream with a threshold to determine (88), on a pixel-by-pixel basis, whether any particular pixel lies on or outside one of the laser lines received by the camera. For a pixel lying on a laser line, the comparator interrupts (IRQ) operation of the microprocessor (80) which then determines the position within the image of that pixel and uses that information to generate the coordinate output data.
