The optical device for determining the angular position of a rotating element comprises: a concave mirror (13) integral to one rotating element (7); an electromagnetic radiation emitter (17); at least one electro-optical detector (19R, 19L). The concave mirror, the emitter, and the detector are arranged in such a way that at least a part of the radiation emitted by said emitter is focused by the concave mirror on said at least one detector. The detector produces a signal, which can vary as a function of the position in which the radiation is focused by the mirror on the detector
