| Research Abstract |
The non-destructive and non-touched diagnosis methods with using of millimeter wave and terahertz(THz) wave for cultural properties have been developed. THz spectra of different materials were obtained as basic data for material analysis. Millimeter wave imaging and THz wave imaging were experimented basically for painted cultural properties, and also applied to some wooden painted objects and mural paintings. It is possible to visualize the inner structure at near surface of wooden object by imaging with millimeter wave and THz wave. In THz wave imaging with pulsed wave, it is possible to obtain the tomogram and two-dimensional image at a given depth from the surface of material by time domain spectroscopy. It is possible to visualize the structure of foundation layer and flame of paintings by THz-TDS method.
