| Abstract: | The experimental setup of the pulse video thermography nondestructive testing system is introduced in this paper. On the basis of study of testing mechanism and the two conventional methods, namely reflecting method and transmission method, two methods to increase the heat emission for specimen with smaller heat emission coefficient are presented. The application ranges for the two conventional testing methods are also presented. |
