Abstract
A method for working out the angular position of a rotating element, by using at least one fixed light source emitting a light beam in the direction of a fixed sensor, arranging the light source with respect to the rotating element and sensor to induce an interaction between the beam and sensor, and providing a value of the angular position dependent of the sensor's output signal. The method including:
