空间分集抑制涡旋光束大气闪烁指数的研究
Research on scintillation mitigation by spatial diversity for optical vortex beam
摘要
Abstract
In this paper,wave-optics simulation method is used to study the ability of combating turbulence effect for Laguerre-Gauss beams with different transmission ranges,different turbulence strength,and different topological charges.Next,the cases of multiple vortex beams and multiple receiver apertures are also studied.Through analyzing the simulation data,we find that the aperture averaging,transmit and receive diversity can reduce scintillation index,and especially,the transmit diversity have the best ability to combat turbulence effect.关键词
