| 摘 要： | 本文对N.Abramson提出的夹片方法作了进一步改进。提出了测量物体表面三维变形的双参考光像全息散斑夹片新方法。该法能消除物体由于刚体位移而产生的不良影响。并能有效地消除参考光对测量散斑干涉时出现的严重噪音。文中通过对悬臂梁和玻璃钢三点弯断裂试件的测量及分析,证明了提出的方法是可行的。

| Abstract: | An improvement of sandwich method proposed by N. Abramson is suggested. On this paper, sandwich method of image holographic interferometry with two ference beams and speckle interferometry measurement. This method can effectively eliminate the influence of rigid body motion and those of reference light on measuring Young's fringes. Some examples are included to demonstrate the applicability of this method. |
