Spectroscopy and terahertz imaging for sigillography applications

Résumé

This study focuses on the seals of validation, sealing written documents, used in the Western Middle Ages, especially wax seals. We use THz spectroscopy and imaging for non-destructive evaluation of natural materials within those seals. Using a time domain THz spectroscopy and imaging system, THz transmission images are generated in the 0.1-3 THz range and demonstrate that the spectral properties of these materials allow to see across and under a thick layer of old wax.
