| Outline of Final Research Achievements |
The principal investigator had been investigating the imaging technique for plate-like structures such as pipes and tanks in which elastic waves are generated by laser from a distance. This study developed a receiving device for the imaging technique comprising silicone microphones, amplifiers, and a battery. By connecting a Bluetooth transmitter to the microphone unit, the defect imaging was successfully executed by non-contact measurements. Moreover, imaging by remote measurements from a distance of 6 m and image enhancement using six microphones were also successfully confirmed. These are promising results for further applications.
