Beam Profile Analysis: Investigated Gaussian and Laguerre-Gaussian laser beam propagation through atmospheric turbulence.Turbulence-Induced Broadening: Observed beam broadening with FWHM increasing from 50渭m to
Now, we can study an AiB with the OV in atmospheric turbulence. Scintillations are intensity fluctuations arising from the random phase modulation that are induced when an optical beam propagates through the turbulent atmosphere [46]. They are detrimental to the performance of free space optical co...
Optical beams can be distorted when propagating through turbulence, giving rise to power coupling from the transmitted spatial mode into other modes3,24,25,29. In our approach, we consider power coupling among𝓁𝓁modes to characterize such turbulence-induced modal coupling30. Applied to a launch...
《Vertical-Wavefront-Propagation-Through-Atmospheric-Turbulence》是一篇关于大气湍流中垂直波前传播的研究论文。该论文详细探讨了大气湍流对光波传播的影响,特别是在垂直方向上的传播过程。通过数学建模和模拟实验,论文揭示了大气湍流对光波相位的扰动效应,以及这种扰动如何影响光波的传播轨迹和聚焦特性。研究者们提出了一...
Atmospheric TurbulenceTurbulence ParameterThe propagation of spectral Stokes singularities (vortices) of stochastic electromagnetic vortex beams through atmospheric turbulence is studied, where the electromagnetic Gaussian Schell-model (GSM) vortex beam is taken as an illustrative example. It is shown that ...
Propagation properties of coherent and partially coherent beams in atmospheric turbulence are investigated respectively by using numerical simulation. It is found that a partially coherent beam has a spreading larger than a coherent beam. However, from t

We propose and demonstrate a single channel interferometer that can be used to study how vortex beams propagate through a scatterer. The interferometer consists of a multifunctional diffractive optical element (MDOE) synthesized by the spatial random multiplexing of a Fresnel zone plate and a spiral ...
