Outline of Final Research Achievements

An Nd:YAG pulsed laser with a nanosecond order is used to generate a shock wave by laser induced plasma, which is subsequently used as a non-contact, non-destructive excitation force for transparent materials. Then, a polarization high-speed camera measures the generated Lamb wave. In this experiment, an impulse input is generated via a laser-induced plasma shock wave and the phase velocity of the generated Lamb wave in the polycarbonate plate is measured by a polarization high-speed camera. We found that this Lamb wave was in the S0 mode. Observing its propagation can detect scratches on the order of several dozen micrometer on the surface of a transparent plate in a non-contact, non-destructive manner.

Academic Significance and Societal Importance of the Research Achievements

透明体材料は,タブレット端末やスマートフォンなどの普及に伴い,その需要が近年拡大している.大量に高品質なものを提供するためには,数十マイクロメートルスケールの小さな損傷を迅速に検知し,品質を評価することが重要となる.本手法を用いることで,従来では困難とされてきた,透明体材料の表面につけられた数十マイクロメートルスケールのスクラッチを,数十マイクロ秒の短時間で検知できるようになった.また,本研究を応用することで,従来の機械的な引張試験を実施することなく,非常にやわらかい透明体材料(例えば,ゲル)のヤング率,ポアソン比を非接触非破壊で求めることができるようになった.
