Sky polarization pattern under multi-layer environment of atmosphere and sea fog

The vertical polarization distribution pattern of sea fog multilayer media and skylight in the atmosphere is explored. To change complicated maritime environment, simplified double layer structure employed, scattering coefficients uniform medium are derived using Rayleigh Mie methods, respectively. Using adding-doubling method (RT3) based on vector radiation transmission equation, between two layers calculated to obtain conditions skylight, variation tendency characteristics observed from ground studied for downwelling meridian Sun. An indoor setting was employed perform test, relationship humidity, light intensity transmittance, degree data suggest that Sun’s position gives lowest (DOP), maximum value obtained when angle solar altitude 90°. Short wavelength lasers have a higher influence optical transmittance than long do humidity levels increase. circular effect laser better damp surroundings.
