Abstract

Current mathematical models describing laser propagation through the atmosphere were developed for terrestrial environments. An atmospheric index of refraction power spectrum specifically tailored to the marine environment has been created and applied to scintillation theory. Optical measurements of a diverge laser beam propagating in a marine environment, in combination with scintillation theory and a numerical scheme, were used to infer the refractive index structure parameter, C_n², along the propagation paths. The analysis was repeated for both marine and terrestrial theoretical scintillation expressions, each resulting in one set of inferred C_n²-values. In the moderate-to-strong fluctuation regime, the inferred C_n²-values based on marine theory were about 20% smaller than those based on terrestrial theory, but a minimal difference was observed in the weak fluctuation regime.
