Indoor visible light OAM multicast communication system

ActiveCN106982095AInterference-free receptionSolve the problem of communication blind spotsClose-range type systemsMultiplexingSpatial light modulator
The invention discloses an indoor visible light OAM multicast communication system. The downlink of the system generates, by a laser device LD, a Gaussian beam in which multicast information is modulated. A collimated laser is converted into an OAM beam with a spiral phase via a two-dimensional laser beam splitter and a spatial light modulator. When modulating the spiral phase of the OAM beam, the spatial light modulator expands the coverage area of each beam by spinning the beam. Further, the irradiation areas of respective beams are overlapped so as to compensate for the central dark spot of a single beam, thereby achieving non-blind area transmission. For the multicast communication system, uplink communication is performed by means of an LED wavelength division multiplexing mode so as to achieve non-blind area two-way data interaction in a system. In addition, the indoor visible light OAM multicast communication system can greatly improve the communication capacity of the downlink of the system by using an OAM multiplexing technique, and is higher in communication efficiency.
