A series of methods for generating vortex beams are described and compared in detail. Laguerre-Gaussian and Bessel-Gaussian beams are taken as examples to introduce the transport properties of vortex beams in atmospheric turbulence. The authors show that superposition of vortex beam state, interference, diffraction, and grating can realize the detection of the topological charge of vortex beams. The authors also introduce the application of vortex beams in optical communication and the transmission characteristics of partially coherent vortex beams in atmospheric turbulence. Finally, the authors describe vortex beam information exchange and channel reconstruction.Optical Wireless Communication Theory and Technology,2731-5975TelecommunicationOptical communicationsLasersMicrowaves, RF Engineering and Optical CommunicationsOptical CommunicationsLaserTelecommunication.Optical communications.Lasers.Microwaves, RF Engineering and Optical Communications.Optical Communications.Laser.621.366Ke Xizheng1217647MiAaPQMiAaPQMiAaPQ9910717413103321Generation, Transmission, Detection, and Application of Vortex Beams3294417UNINA
