反常涡旋光束在湍流大气中的传输特性研究
Propagation Properties of Anomalous Vortex Beams in Turbulent Atmosphere
摘要
Abstract
Based on the Huygens -Fresnel principle,a closed -form propagation formula of anomalous vortex beams in atmos-pheric turbulence are derived.The influence of the atmospheric constant of refraction index structure and the beam size on the propaga-tion characteristics are studied.The numerical simulations show that,in the same observation plane,the dark spot size of vortex beams decreases gradually and eventually disappear with the increase of refractive index structure constant.Furthermore,for the same atmos-pheric refraction rate,the dark spot size of the vortex beam decrease gradually with the increase of propagation distance.关键词
