The Terahertz imaging technique was applied to observe the preparation layer of wall paintings. The experimental results revealed the effect of the particle size of fillers and the possibility of internal interface observation by the THz pulse-echo imaging.

Terahertz (THz) spectroscopy and THz imaging techniques are expected to have great potential for the noninvasive analysis of works of art. THz waves can penetrate opaque materials and have the potential to non-destructively create three-dimensional maps of materials by spectroscopic imaging. Satisfactory results using model samples have been obtained by many institutions. We have succeeded in the...
Terahertz imaging was applied to examine East Asian artworks. The reflection image indicates a material map, and detached area is clearly observed as the distribution of air gaps. These results prove that terahertz imaging can be a new diagnosis tool of deterioration of artworks.
