An optical steering angle sensor for determining the absolute value of the steering angle even when a steering wheel has been revolved several times is provided, having a stator, a rotor with a barcode and evaluation electronics. In one form, the invention provides for the rotor to have a track groove which is arranged in the form of a worm in order to determine the number of revolutions, which track groove has an associated driver finger on the stator, which engages in the track groove and is arranged in a bearing such that it can pivot, and has a holder for a magnet which can pivot with the driver finger and which driver finger has an associated stationary Hall sensor, which is provided in an evaluation circuit.
