| Abstract: | Various nondestructive testing techniques and their characteristics are briefly described. Special attention is paid to ESPI. It has the advantages of noncontact, high precision, high sensitivity, wide frequency bandwidth, rapid and full-field and has a promising future in the engineering practice. But there are still some key problems that should be solved before it is used in practice such as the low anti- disturbance capability and low signal-to-noise ratio. Several image processing methods for interference fringe are presented also. |
