CRACK DETECTION SYSTEM AND METHOD |
摘要 |
A crack detection system and method thereof are disclosed. Wherein, the crack detection system comprises: a laser (10) for producing a pulse laser; an optical path adjusting device (20) for adjusting the optical path of the pulse laser produced by the laser (10) and then projecting the laser on a crack detection surface of a workpiece to scan the crack detection surface with the laser; a signal receiving device (30) for capturing thermal excitation ultrasonic wave signal generated by the crack detection workpiece scanned by the laser; an imaging device (40) for generating a dynamic waveform image based on the thermal excitation ultrasonic wave signal received by the signal receiving device (30).
