Abstract

Modern atmospheric modeling tools and beam control systems do not account for beam degradation along the propagation path due to real-time weather-induced scintillation. Typically, the effect of atmospheric phase turbulence on Gaussian beam propagation is limited to a global scintillation index (SI) and the resulting fringe visibility over the propagation path; however, this model is insufficient when the propagation path traverses multiple, time-varying weather conditions with varying scintillation properties. The proposed model iterates on existing atmospheric modeling tools to include scintillation physics via Mie scattering. These scattering calculations may then be implemented as sub-steps inside the Split-Step Beam Propagation Method to account for time- and path-dependent scattering.
