PURPOSE: A non-contact type imaging device for a nondestructive inspection and a method thereof are provided to sense even a small damage with the high reliability by forming guided wave images having a spatial resolution and temporal resolution. CONSTITUTION: A non-contact type imaging device for a nondestructive inspection comprises a laser generating unit(10), a measuring unit(20), and an image processing unit(30). The laser generating unit irradiates pulse lasers to a structure(40) and emits guided waves to the structure. The measuring unit measured the guided waves generated in the structure in non-contact type. The image processing unit portrays converts the measured data into images and extracts automatically distinguishes damage information. |
