Non destructive testing in situ, of works of art by stimulated infra-red thermography

Stimulated infra-red thermography emerges as a powerful, non-destructive tool for detecting hidden defects in historic mural paintings. This study demonstrates its effectiveness in identifying separations and air voids in renowned works of art, including the UNESCO-listed Abbey Church of Saint-Savin sur Gartempe, the Louvre’s Saint Christopher, and Jean Cocteau’s frescoes in Villefranche-sur-Mer. The technique relies on thermal imaging to reveal subsurface anomalies without physical intervention, offering invaluable insights for conservation efforts. By analyzing temperature variations induced by infrared stimulation, researchers can pinpoint areas of delamination or deterioration, enabling targeted restoration interventions while preserving cultural heritage.
