Non-invasive techniques and methods for diagnostics applied to cultural heritage and knowledge of constituent materials

Abstract

This special session explores non-invasive diagnostic techniques that use imaging and precise measurement systems to investigate, characterize, and document the materials that make up cultural heritage. Techniques based on different wavelengths of the electromagnetic spectrum enable varying degrees of penetration and allow researchers to analyze internal structures, artistic methods, previous restoration interventions, and degradation processes.

From ultraviolet to terahertz radiation, these diagnostic approaches support in-depth knowledge of constitutive materials and surface treatments while preserving the physical integrity of the artwork. The session welcomes contributions that employ Raman spectroscopy, hyperspectral and multispectral imaging, ultraviolet fluorescence, infrared spectroscopy, infrared reflectography, FTIR analytical methods, and terahertz-based imaging for heritage analysis and conservation.
