ABSTRACT:
A device for transmitting light signals between two structural members rotating relative to one another about an axis of rotation, one of these members bearing a light emitter, preferably a light conductor, and the other bearing a photoelectric transducer placed opposite the light emitter so as to leave a gap therebetween, the transducer converting the light signals received into electrical signals. The light emitter emits light through an emission opening provided at a predetermined distance from the axis of rotation. An annular photoelectric transducer which is centered relative to the axis of rotation is located opposite the emission opening and is irradiated by the light emerging therefrom.
