Analysis of temporal power spectra for optical waves propagating through weak anisotropic non-Kolmogorov turbulence

Journal of the Optical Society of America A, 2015
Analytic expressions for the temporal power spectra of irradiance fluctuations and angle of arrival (AOA) fluctuations are derived for optical waves propagating through weak anisotropic non-Kolmogorov atmospheric turbulence. In the derivation, the anisotropic non-Kolmogorov spectrum is adopted, which adopts the assumption of circular symmetry in the ...

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 ...

Analytical expressions for the log-amplitude correlation function for plane wave propagation in anisotropic non-Kolmogorov refractive turbulence

Journal of the Optical Society of America A, 2012
An analytical expression for the log-amplitude correlation function for plane wave propagation through anisotropic non-Kolmogorov turbulent atmosphere is derived. The closed-form analytic results are based on the Rytov approximation. These results agree well with wave optics simulation based on the more general Fresnel approximation as well as with ...

Performance of wireless optical communication systems based on polarization shift keying modulation over anisotropic non-Kolmogorov turbulence

2018 Asia Communications and Photonics Conference (ACP), 2018
We investigated the performance of wireless optical communication systems with polarization shift keying modulation when the atmospheric turbulence is anisotropic. Based on the unified theory of polarization and coherence, the characteristic of polarization crosstalk on propagation was shown.

Visualizing the effects of distributed volume non-Kolmogorov and anisotropic turbulence on incoherent long horizontal-path imaging

SPIE Proceedings, 2014
Video imagery is extremely useful in developing an intuitive sense for the effects of atmospheric turbulence in long, horizontal-path imaging. This is especially true when attempting to understand the effects of Non-Kolmogorov and anisotropic turbulence.

Beam spread and wander of Gaussian beam through anisotropic non-Kolmogorov atmospheric turbulence for optical wireless communication

2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017
In the horizontal atmospheric turbulent channel of optical wireless communication (OWC), anisotropy has been proved to be one of essential properties. This paper investigates the long term beam spread and the beam wander of Gaussian beam based on the generalized anisotropic non-Kolmogorov power spectrum, where all the influence of the anisotropy of ...
