Anisotropic non-Kolmogorov turbulence phase screens with variable orientation

Applied Optics, 2015
We describe a modification to fast Fourier transform (FFT)-based, subharmonic, phase screen generation techniques that accounts for non-Kolmogorov and anisotropic turbulence. Our model also allows for the angle of anisotropy to vary in the plane orthogonal to the direction of propagation. In addition, turbulence strength in our model is specified via a

SLM-based laboratory simulations of Kolmogorov and non-Kolmogorov anisotropic turbulence

Applied Optics, 2015
In this paper, we present a laboratory setup to simulate anisotropic, non-Kolmogorov turbulence. A sequence of numerical phase screens that incorporate the turbulence characteristics were applied to a spatial light modulator placed in the path of a laser beam with a Gaussian intensity profile and the resulting far-field intensity patterns were recorded

Deep turbulence propagation of a Gaussian-beam wave in anisotropic non-Kolmogorov turbulence

Proceedings of SPIE, 2013
In the conventional Kolmogorov model of turbulence the turbulent fluctuations of the index of refraction are assumed to be statistically homogeneous and isotropic, and there is a specific mathematical form for the power spectral density of the index of refraction fluctuations.

Atmospheric turbulence MTF for optical waves׳ propagation through anisotropic non-Kolmogorov atmospheric turbulence

Optics and Laser Technology, 2014
Abstract The conventional investigations for atmospheric turbulence have assumed that the refractive-index fluctuations of atmosphere are statistically homogeneous and isotropic. Developments of experimental and theoretical investigations have shown that the isotropic turbulence generally exists near the ground, and in the free atmosphere layer above

Effect of anisotropic non-Kolmogorov turbulence on the evolution behavior of Gaussian Schell-model vortex beams

Optics Communications, 2019
Abstract The effect of anisotropic non-Kolmogorov turbulence on the evolution behavior of average intensity and coherent vortices for Gaussian Schell-model (GSM) vortex beams is investigated. Based on the extended Huygens–Fresnel principle and power spectrum of the anisotropic non-Kolmogorov turbulence, the analytical expressions for the cross ...

Polarization of quantization Gaussian Schell-beams through anisotropic non-Kolmogorov turbulence of marine-atmosphere

Optics Communications, 2016
Abstract Polarization and spatial coherence of quantization Gaussian Schell-beams propagating through the anisotropic non-Kolmogorov turbulence of marine-atmosphere channel are studied based on the quantized Huygens–Fresnel principle and the degree of quantum polarization.
