When structured light is propagated through the atmosphere, turbulence results in modal scattering and distortions. An extensively studied example is that of light carrying orbital angular momentum (OAM), where the atmosphere is treated as a phase ...

Vehicle-induced turbulence and atmospheric pollution [PDF]
Theoretical models of the Earth's atmosphere adhere to an underlying concept of flow driven by radiative transfer and the nature of the surface over which the flow is taking place: heat from the sun and/or anthropogenic sources are the sole sources of ...

Temporal and spatial variation of refractive index structure coefficient over South China sea
Turbulence is a scientific problem that has not been solved completely for 300 years. Turbulence is brought out by buoyancy heat bubble and wind shear, which transports matter and energy between the earth’s surface and the atmosphere.

An Atmospheric Turbulence Probe
In this paper, a complete low-cost atmospheric turbulence probe, capable of measuring temperature, differential temperature, humidity, horizontal wind speed and direction, and vertical wind component is described. Special care has been taken to minimize the probe's weight so that it may be carried easily by a balloon.

Blind atmospheric turbulence deconvolution [PDF]
A new blind image deconvolution technique is developed for atmospheric turbulence deblurring to overcome limitations of ‘generic’ blind deconvolution algorithms that do not take into account the complicated physics of the turbulence. The originality of the proposed approach relies on an actual physical model, known as the Fried kernel, that quantifies ...
