Novel Detection of Atmospheric Turbulence Profile Using Mie-Scattering Lidar Based on Non-Kolmogorov Turbulence Theory [PDF]
Entropy, 2023 Turbulence can cause effects such as light intensity fluctuations and phase fluctuations when a laser is transmitted in the atmosphere, which has serious impacts on a number of optical engineering application effects and on climate improvement. Therefore,

Novel Simulation and Analysis of Mie-Scattering Lidar for Detecting Atmospheric Turbulence Based on Non-Kolmogorov Turbulence Power Spectrum Model [PDF]
Entropy, 2022 The Mie-scattering lidar can detect atmospheric turbulence intensity by using the return signals of Gaussian beams at different heights. The power spectrum method and Zernike polynomial method are used to simulate the non-Kolmogorov turbulent phase plate,

Non-Kolmogorov atmospheric turbulence and optical signal propagation [PDF]
Nonlinear Processes in Geophysics, 2006 In the present review, we make an attempt to attract attention to the effect of non-Kolmogorov behavior of turbulence in various scales on the characteristics of electromagnetic waves propagation through a turbulent atmosphere on the example of certain ...

Oceanic non-Kolmogorov optical turbulence and spherical wave propagation
Optics Express, 2021 Light propagation in turbulent media is conventionally studied with the help of the spatio-temporal power spectra of the refractive index fluctuations. In particular, for natural water turbulence several models for the spatial power spectra have been developed based on the classic, Kolmogorov postulates.

Engineering turbulence resilience in Bessel-Vortex beams through partial coherence and topological charge pairing [PDF]
Scientific ReportsEngineering optical resilience against atmospheric turbulence is essential for robust free-space photonic technologies. Here, we demonstrate that dual partially coherent Bessel-Vortex beams—with engineered topological charge pairing—exhibit unprecedented
