| 摘 要： | 在材料力学中,金属梁的挠曲线是一个微小的位移分布,无法用常规测量方法精确测量。论述了利用激光全息技术再现金属梁挠度的方法。同时根据挠曲线的数值解,计算出挠度的理论分布,计算结果与激光全息实验符合得很好。这表明激光全息技术可为材料的挠度研究提供新的直观、有效的检测方法。

| Abstract: | In the material mechanics,the deflection of metal girder is a minute movement,and can't be measured using the normal regulation.This paper discusses the method of recurrence of the deflection of metal bar by means of holography,and calculates the deflection of metal bar according to the theory of deflection.The computing result is well in accordance with that of the laser holographic experiment,which proves that laser holography is a new intuitional and effective study method for metal material. |

| Keywords: | deflection holography micro-displace precision measurement |
