Abstract :
Dielectric properties of wood were estimated by a reflection imaging using monostatic system of millimeter wave of 100GHz and by a transmission imaging using bistatic system, respectively. The influence of cellular structure, moisture content and inner defect on the imaging performance was clarified. The feasibility of the millimeter imaging as the tool for nondestructive evaluation of quality and deterioration of wood and wooden structure was confirmed.
