| 摘 要： | 应用Mie散射理论，在散射角0～π范围内，模拟微球体颗粒的散射光强度与粒径大小的变化关系，分析了相对折射率的大小对散射光强度的影响；在实验装置条件下，分别模拟了散射光强度与粒径大小的变化关系及2um、5um、10um三种粒子的散射光强度与波长的变化关系。实验验证了数值模拟与实验结果基本一致，也证明实验中粒子散射遵从Mie散射理论模型。

| Abstract: | The theoretical simulations of the relations between the scattering intensity of microsphere particle and particle dimension are carried out with Mie scattering theory. The relation between the relatively refractive index and scattering light intensity is analysed. The scattering intensity versus the particle dimension and the exciting wavelength are studied experimentally. It is verified that numerical simulations are agree with the experiment result, so the scattering of particles in micrometer level obey the Mie scattering theory. |
