Claim 5:
6. The detection system as claimed in claim 4, further comprising
a second support secured to the support or forming an integral part of the support, comprising a series of N windows uniformly distributed angularly around a circular periphery centered with respect to the axis of rotation (Δ) of the support, said series of N windows comprising a reference window of different size from the other windows, the other windows being indexed with respect to this reference window,
an optical fork, the optical fork being provided with an emitter configured to emit a light wave and a detector configured to detect the light wave, said fork being configured to generate electrical pulses when, on any one of the windows passing between the emitter and the receiver, the receiver receives the light wave,, the processing unit being configured to determine the first and second angular positions based on the indexes of the two windows that have produced the electrical pulses which are temporally closest to the two successive times for which the detection by the detection element (DT) has taken place.
