Propagation properties of partially coherent radially polarized doughnut beam in turbulent ocean

Based on the extended Huygens-Fresnel integral principle and unified theory of coherence and polarization of light, the change in various propagation properties of partially coherent radially polarized doughnut (PCRPD) beam through the turbulent ocean is studied. The ocean-induced fluctuations in the refractive index are assumed to be driven by temperature and salinity fluctuations. Numerical examples of change in the optical intensity, degree of polarization, degree of coherence are presented for the PCRPD beam. The results show that the oceanic turbulence parameters and the initial parameters of light source have significant influence on the intensity, degree of polarization, and degree of coherence for the PCRPD beam.
