白光散斑和超声C扫描用于复合材料缺陷检测

The White Light Speckle and Ultrasonic C-scanning Used to Detect Defects of Composite

用白光散斑法和超声Ｃ扫描相结合的方法检测复合材料内部缺陷；并用ＧＴＦ—１８２光学图象数字分析系统对白光散斑法所得经付氏变换的图片进行了处理。给出了这两种方法检测碳／环氧层板分层缺陷的实例．

Using the white light speckle and ultrasonic C-scanning method, the internal defects of composite laminate are detected, and a GTF- 182 optical patten digital system is used to analysis white speckle plate that had Fourier thansformed. For an example, the C-epoxy laminate layer defects had detected, using the two methods.
