利用激光干涉条纹的位相，提出了一种简便、快速且精度很高的微小位移的测量方法。
Used the phase of laser interference fringes, a simple, fast and accurate micro displacement measuring method is proposed.
结果表明：文中提出的干涉条纹的细化方法可以准确地找到骨架线，为获得面内位移场的等位移线图提供了一种新方法。
The result shows that the method can find the skeleton lines precisely and provide a new method for achieving the line of equal displacement in the plane displacement field.
当物体上没有零位移区域时，双曝光全息干涉图上便找不到零级条纹。
If there are no areas with zero-displacement on an object, there exist no zero-order fringes on the holographic interferograms.
