In this paper the reason of signal loss is analysed and the method of calculationg the lost fringe number is described.
分析了信号丢失的原因，给出了丢失条纹数的确定方法。
With increasing beam separation, the number of interference fringes increases and the fringe separation and visibility decrease.
随着光束间距的增大，干涉条纹间距减小，条纹数目增多，条纹可见度减小；
A detection system for counting shift number of interference fringe is established.
在检测系统中实现了对干涉条纹移动量的计数。
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.
理论分析表明从从荧光干涉条纹的强度分布中可获得关于俘获原子总数以及密度分布的信息。
