| 摘 要： | 通过对简支梁受力前后的双曝光全息图进行再现，利用透过全息图的条纹解释办法，分别用目测和数字图像处理办法测量物面上干涉条纹间距，从而得出简支梁的挠度；再利用最小二乘法求出被测物件的弹性模量。

| 关 键 词： | 干涉条纹 条纹间距 弹性模量 简支梁 |

| Abstract: | The author reproduces double-exposure hologram of simple beam before and after stress,measures interference fringes spacing of objects' surface through visual measuring and digital image processing by the stripe explanation through the hologram and succeeds in obtaining simple beam deflection and Young's modulus of the objects using least-square method. |
| |
| Keywords: | interference fringe distance of fringe Young's modulus simple beam |
