Abstract(in English) | There is a scanning laser source technique (SLS) for performing high-speed measurement by scanning a laser excitation source two-dimensionally. In this study, we aimed to realize an elastic wave source scanning method using high-intensity aerial ultrasonic waves as an elastic wave source. If this elastic wave source scanning can be performed by aerial ultrasonic wave, not only the range of the measurement target will be expanded, but also the miniaturization and simplification of the measurement system are expected. One way to realize this measurement technique is to introduce an aerial ultrasound phased array (AUPA). In this report, we proposed and verified an elastic wave source scanning method using the AUPA as a basic study. Specifically, a phased array device that generates high-intensity aerial focused ultrasonic wave has been prototyped, and non-contact and nondestructive inspection of solid materials with defects using the elastic wave source scanning method has been attempted using the prototyped the AUPA. |
