Abstract
In a method and apparatus for optically measuring an angle between the positions of components relative to each other, such as the wheels of a motor vehicle, in a vertical plane, light beams are directed along the sides of the angle to be measured. One light beam which is directed along one side of the angle is maintained in respect of its direction, while the light beam directed along the other side of the angle is deflected by the effect of the force of gravity.
