Scattering and Transmission Characteristics of 0.55 μm Laser in Haze with Complex Components
Based on the analysis of extinction, absorption, scattering cross sections, asymmetry factor parameters and particle size distribution function of several typical kinds of haze particles, the transmission and scattering characteristics of 0.55 μm laser in haze media with different components and different mixing modes are studied by Monte Carlo method, and the effects of several typical kinds of pollutant particles on light transmittance are also compared. The results show that at the same concentration, the transmittance in ammonium sulfate medium is the highest and that in carbon aerosol medium is the lowest, and the transmittance in fog is less than that in haze. The comparative analysis of the transmittance in the medium composed of cluster particles in different mixed modes shows that the attenuation of light by typical pollutant particles in external mixing mode or in internal mixing mode is almost the same, while the distribution of water components in the medium has an obvious effect on the transmittance of laser beam.
