摘要：

根据垂直扫描干涉技术结合样品折射率与密度间的依赖关系，建立了低密度SiO2泡沫微球密度的检测方法，用Lorentz-Lorenz和Gladstone-Dale公式分析了SiO2泡沫微球折射率与密度间的依赖关系。实验结果和测量误差估计表明，利用垂直扫描干涉技术并结合Gladstone-Dale分析方法，可实现对低密度SiO2泡沫微球密度的精密检测，其测量误差好于5%。

Abstract:

The measuring method based on vertical scanning interference and combined with the relation between refraction index and density of SiO2 foam shells is introduced, and the relation is analyzed according to formulas of Lorentz-Lorenz and Gladstone-Dale. The experimental result and measuring uncertainty evaluation indicate that the precision measurement of density of low density SiO2 foam shells can be realized by using the vertical scanning interference technique and combining with Gladstone & Dale analysis method, and the measuring uncertainty is about 5%.

Key words: SiO2 foam shell, Density measurement, Vertical scanning interference, Refraction index, Inertial confinement fusion
