Investigation on the scintillation reduction of elliptical vortex beams propagating in atmospheric turbulence
Atmospheric optics Free-space optical communication

We numerically investigate the scintillation index of an elliptical vortex beam in both modest turbulence and strong turbulence. Numerical simulations are realized with random phase screen sc...
Experimental investigation on the scintillation index of vortex beams propagating in simulated atmospheric turbulence
Experimental investigation scintillation index vortex beams propagating simulated atmospheric turbulence
2013/7/3
The scintillation index of vortex beam in simu-lated atmospheric turbulence is experimentally investigated.The fluctuation of the intensity can be effectively reduced by vortex beams. In particular, t...
In the paper, a method to calculate the time evolution turbulence wavefronts based on the covariance method is theoretically presented in detail. According to it, the time-evolution wavefronts disturb...
