THz techniques as a complementary non-invasive diagnostic method for the study of medieval panel paintings

摘要

Terahertz spectroscopy and imaging techniques have been successfully applied to non-invasively investigate cultural heritage objects. One of the advantages of terahertz time domain imaging is that cross section images can be obtained without surface contact only by using a terahertz pulse. Experimental results revealed the presence of different preparation techniques in two medieval tempera masterpieces.
