Through the application of terahertz spectroscopy and imaging to the analysis of art, we have developed a spectral database of art materials containing more than 200 spectra of various pigments and binders. With this database, a red ink used in a thirteenth-century manuscript was identified; the results were verified by X-ray fluorescence elements mapping. Terahertz transmission spectral component...
Recently terahertz spectroscopy has progressed rapidly and it is expected that its spectra are more material specific compared with those of mid-infrared regions. Since the materials used in art are basically mixtures and are composed with inorganic and organic materials, spectra obtained in mid-infrared regions are complicated. We have observed spectra of various historical and modern pigments and...
The scientific analysis is an important process in art conservation for collecting information of materials used in original work as well as in previous conservation processes. Recently terahertz spectroscopy has progressed rapidly and it is expected that its spectra are more material specific compared with those of mid-infrared regions, so that it can give useful information to identify materials...
