| 摘 要： | 从光学几何关系出发,推导了在平行光照明、物体沿散斑片纵向方向微小移动情况下的一种全息干涉条纹的解释方法.该方法可以根据任一瞬间的条纹间距测量物体的位移,并适用于实时全息监测的定量分析,对全息干涉计量术提供有效的条纹解释方法和物体位移的计算方法.

| Abstract: | Using the analogy between optics and geometry,a new explanation of the holographic interference fringes with parallel illumination and the object moving along the longitudinal direction of speckle plane is put forward.Based on this explanation,one can measure the object displacement with the fringe at any instant and analyze the real time holographic quantitatively.We also provide new methods for fringes explanation and displacement calculation in holographic interference measurement technology. |

| Keywords: | holographic interference interference fringe micro-displacement distance of fringe |
