| Abstract: | 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. |
