Abstract

The invention discloses a novel optical communication system and method suitable for a rotary joint. The system comprises a light source, an optical beam expanding lens battery, a wavelength spectroscope, a focusing lens battery, a receiving detector, a reception unit, an emission unit and a conical cavity; a light beam emitted by the light source is collimated by the optical beam expanding lens battery, the collimated light beam is transmitted by the wavelength spectroscope in which reception is separated from transmission; the transmitted light beam is reflected by the surface of the conicalsurface into a circular ring light beam, and the reception unit receives the circular ring light beam; collimated light emitted by the emission unit irradiates the surface of the conical cavity, reflected by the surface of the conical cavity to the wavelength spectroscope, and reflected by the wavelength spectroscope to the focusing lens battery, and the light beam gathered by the focusing lens battery is transmitted to the receiving detector. Bidirectional communication of an emission light ring and optical reception are realized without being influenced by a rotation mechanism, and information interaction can be realized for two servo mechanisms including the internal and external stators or the rotary joint.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a novel optical communication system and method suitable for a rotary joint. Background technique [0002] Communication between rotary joints is often achieved using slip rings. The electrical connection between the rotating end and the fixed end, such as power supply and signal, is transmitted through the conductive slip ring, but the long-term friction between the conductive slip ring contact and the ring body will lead to performance degradation, low reliability, and poor anti-electromagnetic interference. For high-speed digital signal, the transmission attenuation is large, and the communication is unreliable. [0003] The optical fiber slip ring is installed in the traditional mechanical power ring with an optical fiber rotary connector, which is flexibly connected through a mechanical plug-in mechanism. The optical fiber rotary connector uses a single-mode optical...
