| Abstract: | In terms of its high sensitivity and automation, non-destruction test based on photoelectric technique has more advantages in the high-speed automatic detection test and measurement of surface cracks and corrosions in a pipe than traditional methods. The latest development of this technique with the advantages and disadvantages of each kind is gived systematically. The trend of application is also presented. |
