Wave propagation imaging and its applications to structural evaluation

Abstract

In this presentation, principles visualizing propagation of structurally guided waves are first introduced and then several setups and their features are explained. For decades, various wave propagation imaging system has been developed and commercialized for different fields like laser induced ultrasound, microwave, pyroshock, and acoustic emission. Depending on the structures and materials, system variation, especially scanning mechanism is also interested and some examples on real world applications of these systems deepen understanding on the applicability and provides inspiration on potential applications. Lastly, suggestion on the smart hangar and smart twin will be followed.
