摘要
在Mie理论的基础上,从单个球形粒子的散射效率因子出发,得到了1—6μm群体粒子的散射系数。根据布格尔定律导出了群体粒子对激光束的散射光强表达式,在接收器视场角范围内,模拟了散射光强的分布情况,结果表明,沿着激光束的传播方向,散射光强存在比较大的起伏,并且越靠近接收器的视场中轴线,散射光强有减少的趋势。
Based on Mie＇s theory, analyzing the scattering efficiency factor of a spherical particle, the scattering coefficient of 1 - 6μm spherical particles was presented. The expression of the scattering intensity of particles was obtained. Then in the field of view of the receiver, the distribution of scattering intensity was simulated. The simulation results showed that, in the orientation of propagation, the scattering intensity exhibited undulating, and closing with the axial orientation, the scattering intensity exhibited the decreasing trend.
