FIELD: transport engineering.
SUBSTANCE: according to proposed method, wheel section is being scanned by means of light beam radiated by light source 6, and reflected light beam is detected by receiver 7 sensitive to change of position. Distance from section under scanning to initial point is measured account of directions of radiated and reflected beams. Receiver 7 sensitive to change of position is turned synchronously with light source 6 by means of turning device around common axle 4 to provide successive measurements.
EFFECT: facilitated recording of complex characteristics of wheel rim contour.
