Abstract
A system for transferring data between a rotating element and a fixed element by wireless optical communication, including a plurality of rotating optical transmitters distributed in a ring around the turning element and solidly attached to the rotating element, and at least one fixed optical receiver mounted on and solidly attached to the fixed element, arranged at the same height as the plurality of rotating optical transmitters in which the rotating optical transmitters simultaneously transmit a same optical signal, independently of the angular position of the rotating element and are sufficiently numerous such that regardless of the angular position of the rotating element, the fixed optical receiver receives an optical signal.
