摘要

激光束在雾中散射衰减，用于激光通信、激光遥感探测。对于不同密度和雾滴分布，激光散射和衰减是不同的，相应的机制需要深入研究。在平流雾和辐射雾雾滴尺寸特征的基础上，研究了激光束在不同类型雾中的散射特性，计算了不同激光波长(0.86 μm、0.91 μm、1.06 μm、1.3015和10.6 μm)雾滴的散射系数，用蒙特卡罗方法研究了激光束的多重散射，分析了光子的传播路径和散射方向，给出了雾滴的反照率和能见度，并对雾滴的前向散射强度和后向散射强度与散射角的关系进行了讨论。

The Multiple Scattering of Laser Beam Propagation in Advection Fog and Radiation Fog

The laser beams were scattered and attenuated when they propagate in fogs for laser communication, laser remote sensing detection. For different density and droplets distribution of fogs, the laser scatter and attenuation are different, the correspond mechanism need thorough investigation. The characteristics of laser beam scattering in different types of fogs are studied based on the droplet size characteristics of advection fog and radiation fog, the scattering coefficients of droplets with different laser wavelengths(0.86 μm, 0.91 μm, 1.06 μm, 1.3015, and 10.6 μm) are calculated, the multi scattering of laser beam is studied by the Monte Carlo method, the propagation path and scattering direction of photons is analyzed, relations between asymmetry factor, albedo of fog droplets, and the visibility are presented, and the forward scattering intensity and the backward scattering intensity versus scattering angle are gotten and discussed.

期刊介绍： International Journal of Optics publishes papers on the nature of light, its properties and behaviours, and its interaction with matter. The journal considers both fundamental and highly applied studies, especially those that promise technological solutions for the next generation of systems and devices. As well as original research, International Journal of Optics also publishes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
