Spectroscopy and terahertz imaging for sigillography applications

Abstract

Sigillography is the science that studies the manifold aspects of the seals. A seal can be defined as an imprint obtained on a malleable medium by imprinting an incised matrix, which transfers on it the characteristic signs of a person or an institution. We use THz spectroscopy and imaging for non-destructive evaluation of natural seals. Using a time domain THz spectroscopy and imaging system, THz transmission images are generated in the 0.1–3 THz range.
