| 摘 要： | 实验观察来自磁光阱中冷原子团的荧光经真空系统窗口的平板玻璃反射产生的干涉条纹，理论分析表明从从荧光干涉条纹的强度分布可获得关于俘获原子总数以及密度分布的信息。采用该方法实测了俘获原子总数，并模拟得到了不同密度分布时条纹的对比度变化。

| Abstract: | It is observed that the interfering fringe produced by two virtual images of cold in a magneto|optical trap (MOT) atom cloud presenting on a plane glass of a low-vapour-pressure cell. Using the fringe the number of trapped atoms are estimated. And from contrast of the fringe the information about density disturb of atom cloud can be got. |

| Keywords: | cold atom cloud interfering fringes density distribution |
