| 摘 要： | 对光导纤维—数字散斑相关方法进行了详细的理论分析和实验研究。作者根据相关搜索法的基本思想．按照ＭＳ４２１３型图像板的存取模式，用Ｃ语言编写了专门的相关识别程序。利用光纤完成了刚体（定轴转动圆盘）全场位移测量和变形体（三点弯曲梁）挠度全场测量的两个验证性实验，实验结果与理论值吻合较好。

| Abstract: | Optical fiber-digital speckle pattern correlation method (FDSP) is studied based on theoretical analysis and experimental research. The writers have created special program for image correlation analysis written in C langUage,according to the basic idea of digital speckle pattern correlation searching and reading/ writing mode of MS4213 image board.The experiment verification of displacement measurement of rigid body (turned disc) and deflection measurement of deformed body (three-point bending beam) have been achieved,and experimental values are coincident with theoretical values. |
