| Abstract: |
| In this paper, a non-destructive detection method based on locked-in infrared thermal imaging is used to detect OSR bonding inerface defects. The technical principle of infrared thermal imaging detection method is analyzed, samples with natural defects are maded, and the detection ability of infrared thermal imaging edtecton methods are researched.The results show that, thermal miaging detection method based on infrared phase locked-in can effectively detect the holes in the OSR bonding interface in actual combat, the smallest defect size that can be detected is 1.5mm, and the method has hight detection sensitivity. |
