| 摘 要： | 介绍了电子散斑干涉计量（ＥＳＰＩ）原理，推导了ＥＳＰＩ求挠度（离面位移）的公式，设计了测量悬臂板离面位移的光路，用Ｃ语言编制了相应的数字图象处理软件，得出相关条纹图，计算了悬臂板的离面位移，并与双曝光全息干涉法作了测试比较，结果很好符合。

| Abstract: | n th is paper,a procedne of Electronic Speckle Parttern Interferometry(BPI)is intro-duced,and the deflection of a cantilever plate is deduced by using the method.Schematics of the optical setnp is presented. According to correlation fringes obtained, deflection distri-butlon of the cantilever plate can be calculated.Comparison of the result obtained by this niethod and that by Double-exposure Holographic Interferometry shows that the two results are in good agreement. |
