| Research Abstract |
Wood identification often provides invaluable information in various aspects of historical and cultural affairs. So far, the technique of discerning the morphological features by optical microscopic observation, is most commonly used.Although it is a simple procedure, expertise of wood anatomy as well as skills in sample preparation and furthermore experiences are prerequisite. In addition, for instance, wooden objects from national treasure class, the objects, are normally the subject of religion and not the subject of scientific investigation. Therefore, novel non-destructive approach is demanded as an alternative to the conventional microsocpic method.
In vew of such situations, we have investigated (1) 3D imaging using synchrotron X-ray computed tomography(CT), (2) chemical assessment using emitted volatile organic compound(VOC) from wood sample, (3) spectroscopic classification and discrimination by infra-red, near-infra-red, and Raman regions.
