Abstract
The optical device for determining the angular position of a rotating element comprises: a concave mirror () integral to one rotating element (); an electromagnetic radiation emitter (); at least one electro-optical detector (R,L). 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.
