摘要: 利用Mie散射与Fraunhofer衍射理论的数值计算,对球形颗粒的Mie散射和Fraunhofer衍射做了大量的计算和分析比较,提出了大颗粒的Fraunhofer衍射近似替代Mie散射的判据.Abstract: In this paper,based on Mie scattering and Fraunhofer diffraction theory,we utilize the numerical calculation to compare and analyze the Mie scattering and Fraunhofer diffraction of large particles and point out that at a proper range,Fraunhofer diffraction of large particles can approximately replace Mie scattering.
