| Outline of Final Research Achievements |
We developed the engineering wood nondestructive evaluation method by THz electromagnetic wave with high permeability to wood and high safety. A series of studies have shown that it is possible to estimate the density, moisture content and fiber orientation of plywood with high accuracy and non-destructiveness by THz time domain spectroscopy. It was also possible to characterize the adhesive used in plywood. In addition, the imaging of the above properties and the diagnostic potential of each layer of plywood have also been suggested.

| Academic Significance and Societal Importance of the Research Achievements |
THz時間領域分光法によってエンジニアリングウッドの密度・繊維走向・接着材評価が可能であることが分かった。今後装置の小型化・低価格化が進みエンジニアリングウッド製造工場への導入（製造ラインにおけるエンジニアリングの非破壊・非接触品質評価）ができれば、品質の安心・安全対策、製造プロセスの最適化、製造コストの削減および木質資源の有効利用を達成できる。
