Embodiment Construction

[0008] In order to better understand the principles and features of the present invention, further description will be made below in conjunction with specific implementation examples and accompanying drawings.

[0009] figure 1 Shown is a schematic diagram of a portable flashlight excitation thermal wave nondestructive testing system, the system includes a flashlight unit 15, an infrared thermal imager 13, a flashlight power supply 16, a flashlight control module 11, a stabilized power supply 17, a data processing unit 14, and a touch screen display 23 , and a rechargeable battery 19 . Flashlight unit 15 is made up of parts such as high-power flashlight tube, reflector and cooling fan. The flash lamp power supply 16 is composed of a high-voltage charging circuit and a capacitor energy storage device. Driven by it, the high-power flash lamp tube emits a high-intensity short pulse flash 20 and projects it onto the surface of the sample 12 for pulse heating, and the generated he...
