摘　　要：设计了以莫尔条纹为基础的距离测量实验装置;分别做了莫尔条纹栅距B与两光栅夹角θ的关系实验和两光栅相对移动距离d与莫尔条纹明暗变化次数N的关系实验,并将实验中的数据与理论值相比较,从而确定该实验装置的可行性。The article designs an experimental equipment basing on Moire- fringe Method; and using this device, the relation ofthe Moire - fringe interval band the angle θ is analysed; the effect of the grating opposite displacement to the changing time of Moire fringe N is also studied. At last, compare the result of the experiment to the theory, in order to make sure the device＇s reliability.
