Outline of Final Research Achievements

Terahertz waves enables remote non-destructive inspection of buildings such as peeling of tiles. In this research, we have developed a unique terahertz wave source which has ultra-high speed frequency modulation character, enables non-destructive inspection applications. We have successfully developed the novel terahertz-wave source with a measurable distance range of over 3 m and a resolution of 1 mm or less. The novel terahertz wave source with unique measurement characters would open the door to practical non-destructive inspection in the field.
In addition, we developed basic technologies for high-precision imaging of terahertz waves, by introducing analytical methods in radio wave and ultrasonic region.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した周波数シフトテラヘルツ波は、今までに無いオリジナルな動作特性を有するテラヘルツ波光源である。従来のテラヘルツ波による非破壊検査では測定距離レンジの制約などがあり、現場での使用において解決すべき問題が残されていた。本装置の開発によりテラヘルツ波による非破壊検査への応用展開が期待され、建築関連企業との共同研究へと発展している。高度成長期に建設された構造物の老朽化等の社会的問題の解決策の一つとして、安心・安全社会の構築に大きく貢献できる可能性がある。
