摘要

为了解不同类型气溶胶的消光特性及粒子多次散射效应对可见光传输性能的影响,选取400, 488, 550, 694 nm波长和海洋型、沙尘型、水溶性、烟尘4种常见气溶胶,基于Mie散射理论和建立的稳态蒙特卡罗计算模型,研究了可见光的大气传输衰减特性。结果表明,单个粒子散射强度随入射波长的增大而减小;海洋型、水溶性、烟尘粒子的消光效率因子随波长的增大而减小,沙尘型粒子则相反;海洋型、沙尘型、水溶性粒子的消光以散射为主,烟尘粒子则以吸收为主。利用稳态蒙特卡罗方法模拟多次散射效应,结果表明,光波在海洋型气溶胶中透过率最大,在沙尘型、水溶性和烟尘气溶胶中依次减小;随着能见度的增大,透过率逐渐增大。当能见度达到一定程度时,多次散射过程中的吸收作用可以忽略不计。该结论有助于在特定类型气溶胶光学厚成像路径中,构建更加准确的图像退化模型。

Abstract

In order to explore the extinction characteristics of different types of aerosols and effect of multiple scattering on the transmission performance of visible light, four wavelengths of 400, 488, 550, 694 nm and four common aerosols of oceanic, dust-like, water-soluble and soot are selected. Based on the Mie scattering theory and the steady-state Monte Carlo model, the transmission attenuation characteristics of visible light in atmosphere are studied. The results show that the scattering intensity of single particle decreases with the increase of incident wavelength. The extinction efficiency factors of oceanic, water-soluble and soot particles decrease with the increase of wavelength, whereas dust-like particles have opposite effect. The extinction characteristics of oceanic, dust-like and water-soluble particles are dominated by scattering, while soot particles are dominated by absorption. The results of simulation of multiple scattering by steady-state Monte Carlo method show that the transmission rates of light wave in oceanic aerosols, dust-like aerosols, water-soluble aerosols and soot aerosols decrease in turn. The transmission rate increases gradually with the increase of visibility. The absorption effect can be neglected in multiple scattering processes when the visibility reaches a certain degree. This conclusion is helpful to construct a more accurate image degradation model in a imaging path of specific aerosol optical thick.
