Abstract
In a method and apparatus for the optical measurement of an angle between the positions of components relative to each other, such as the wheels of a motor vehicle, a light beam is directed along a first side of the angle to be measured towards the apex thereof and from there is transmitted at intervals of time which each correspond to a full 360.degree. rotation for a first signal registration step at a first moment in time. A second light beam is directed along the second side of the angle to the apex thereof and from there is transmitted, relative to the respective first moment in time, with a time difference corresponding to the angle between the first and second light beams, for a second signal registration operation, at a second moment in time. The magnitude of the angle is calculated from the interval between the two signal registration operations.
