Outline of Final Research Achievements

Identification of wooden heritages has provided beneficial information on the origin, historical background, wood selection and also new perspectives. Destruction of wooden heritages is prohibited. Only non-destructive analysis is allowed.
In this regard, non-destructive and onsite analysis methods has been desired. In this research, near-infrared (NIR) spectroscopy, which is known as a rapid, accurate and reproducible, was applied for wood identification.　When using the non-degraded heartwood materials, we have successfully designed a procedure to identify P. densiflora and P. thunbergii employing a combination of NIR spectroscopy and multivariate analysis. However, evaluation of the models using wood samples from traditional construction indicated that this technique is insufficient to be applied to historical and archeological materials. Therefore, we conclude that further research is required.
