| 摘 要： | 提出了利用单幅电子散斑物体变形相位图分离二维分量的方法.传统电子散斑干涉技术测量得到的是物体变形的混合相位场.当物体具有对称变形时,可通过图像处理的方法,获得二维变形的分量值.利用三点加载的简支梁进行了实验,给出了实验结果,验证了该方法的正确性,该方法保持了传统电子散斑干涉系统的简单、稳定、便于应用的优点,并进一步得到了二维场分量的信息. |
| 关 键 词： | 电子散斑干涉 位移测量 对称变形场 |

| Abstract: | A method about the isolation of two-dimensional displacement for one phase map is presented.When the typical ESPI is used for displacement measurement,a mixed phase distribution of deformation can be measured.If the deformation of the object is symmetrical,two components of deformation can be obtained by image processing.A typical experiment using a three-point-bending is completed.The exerimental results prove correctness of the method.The method presented does not only keep advantages of simpleness,stability and applicability,but also obtain the in-plane displacement and out-plane displacement simultaneously. |
| Keywords: | electronic spckle pattern interferometry(ESPI) displacement measurement symmetrical deformation |
