| 摘 要： | 提出了测量全场应力应变的一种新方法。它可用于测量被测物体整个表面的变形量。这种方法为非接触测量,不影响被测量物的表面。其方法是利用全场激光衍射通过CCD采集计算机成像。编写数字图像处理程序对被测物表面变形信号进行处理取得被测物表面的全场变形信息数据,同时可以观察衍射条纹形貌以及变化全过程。

| Abstract: | Bring forward a new means to test full-court stress and strain. It′s a good way with which we can measure whole surface distortion of object, and needn′t to touch object. The measure mostly depend on combination of laser full-court diffraction and computer imaging with CCD. And then we write photo-processing program to process full-court distortion information. At the same time we can observe whole process of stripe distortion. |
