Propagation characteristics of the vortex beam array through anisotropic non-Kolmogorov maritime atmospheric turbulence

open access: yesFrontiers in Physics, 2023
This study employs the power spectrum inversion method to generate the phase screens of atmospheric turbulence over the sea, the theoretical model of the vortex beam array emitted by a focusing system through anisotropic non-Kolmogorov maritime ...

Computational Imaging Through Atmospheric Turbulence

open access: yesFoundations and Trends® in Computer Graphics and Vision, 2023
Since the seminal work of Andrey Kolmogorov in the early 1940's, imaging through atmospheric turbulence has grown from a pure scientific pursuit to an important subject across a multitude of civilian, space-mission, and national security applications.

A statistical approach to surface renewal: The virtual chamber concept

open access: yesAgrosystems, Geosciences & Environment, 2021
In the stable conditions prevailing at night, concentrations of emitted gases (e.g., radon [Rn], carbon dioxide [CO2], methane [CH4], ammonia [NH3], and nitrous oxide [N2O]) build up at the surface, with intermittent interruptions due to the passage of ...

The fractal turbulent–non-turbulent interface in the atmosphere

open access: yesWind Energy Science, 2023
Abstract. With their constant increase in size, wind turbines are reaching unprecedented heights. Therefore, at these heights, they are influenced by wind conditions that have not yet been studied in detail. With increasing height, a transition to laminar conditions becomes more and more likely.

Transmission Characteristics of Adaptive Compensation for Joint Atmospheric Turbulence Effects on the OAM-Based Wireless Communication System

open access: yesApplied Sciences, 2019
Atmospheric turbulence has an impact on the transmission of electromagnetic vortex waves with an orbital angular momentum (OAM) mode. In this paper, based on the joint atmospheric turbulence model, we examine the influence of atmospheric turbulence on ...

Temporal Variations of the Turbulence Profiles at the Sayan Solar Observatory Site

open access: yesAtmosphere, 2019
The paper focuses on the development of the method to estimate the mean characteristics of the atmospheric turbulence. Using an approach based on the shape of the energy spectrum of atmospheric turbulence over a wide range of spatial and temporal scales,
