We studied a non-destructive inspection method using a guided wave excited by high intensity aerial ultrasonic irradiation. In previous studies, non-destructive inspection was performed using high intensity aerial point-focus ultrasonic waves with high focusing efficency in order to perform multi-frequency imaging using nonlinearity of high intensity acoustic waves. However, there is concern about the effect of multiple scattering on imaging of defects because a spherical guide wave is generated by excitation by point-focused sound waves. In this report, we attempted non-destructive inspection using planar guided waves generated by high intensity aerial line-focus ultrasonic waves. As a result, it was clarified to be possible to imaging of defective area by proposed method. |
