Outline of Final Research Achievements |
Terahertz waves have the characteristic of being able to penetrate obstructions and identify internal reagents, but the lack of cameras operating in this band has required long measurement times for imaging. Therefore, in this research, we have achieved high-speed and high-dynamic-range terahertz imaging by combining our proprietary high-power terahertz source called the injection-seeded terahertz parametric generator (is-TPG) with a method called single-pixel imaging. This allows for the rapid visualization of the spatial distribution of reagents concealed by obstructions, and we expect it to have applications in various fields.

Academic Significance and Societal Importance of the Research Achievements |
テラヘルツ波に期待される応用として、遮蔽物内部の禁止薬物の検出や、薬局での処方薬の間違い検出などが挙げられる。それらの実現には、高速かつ遮蔽物を透過した微弱信号でも測定できる高いダイナミックレンジを有するイメージング手法が必要である。本研究の成果は、まさにそれらの課題を解決しうる実用的なテラヘルツ波イメージングシステムであり、テラヘルツ波を用いた安心安全社会の実現に重要なシステムと考えている。
