Degree of Polarization of Random Electromagnetic Vortex Beams in Atmospheric Turbulence

摘要：

　　Using the extended Huygens-Fresnel principle and the quadratic approximation of the phase structure function,and taking the random electromagnetic Gaussian Schell-model(GSM)vortex beams as a typical example of random electromagnetic vortex beams,the analytical expressions for the cross-spectral density matrix of random electromagnetic GSM vortex beams with topological charge m =+1 propagating through atmospheric turbulence are derived,and used to study the degree of polarization of random electromagnetic GSM vortex beams in atmospheric turbulence and to compare the results of random electromagnetic GSM vortex-free beams.The influence of vortex and atmospheric turbulence on the degree of polarization is analyzed.The validity of our results is interpreted physically.
