Coherent polarization shift keying modulated free space optical links over a Gamma-Gamma turbulence channel [PDF]
Problem statement: The optical signal propagating through the Free Space Optical (FSO) channel suffers from irradiance and phase fluctuations caused by the atmospheric turbulence, which results in Bit Error Rate (BER) performance degradation ...

A statistical approach to surface renewal: The virtual chamber concept
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 ...

Free space optical system performance for a Gaussian beam propagating through non Kolmogorov weak turbulence [PDF]
Atmospheric turbulence has been described for many years by Kolmogorov's power spectral density model because of its simplicity. Unfortunately several experiments have been reported recently that show Kolmogorov theory is sometimes incomplete to describe

Quantitative Analysis of the Effect of Atmospheric Turbulence on a Bessel–Gaussian Beam
Suppressing the impact of atmospheric turbulence on laser beam propagation is a bottleneck problem in the application of free space optical communications, with the primary difficulty being the lack of a quantitative description of the effect of ...
