Photothermal Thermography Applied to the Non-destructive Testing of Different Types of Works of Art

In this article, various cases in helping to restore works of art by stimulated infrared thermography are presented. First, the method allows detecting old restorations found on a mural painting in the French senate. Then, it is demonstrated how the photothermal method enables determination of the underlying structure of the mural painting ??The Apotheosis of Saint Bruno?? in the Charterhouse of Villeneuve-lez-Avignon. Finally, the method allows locating separate canvas paintings on ??Avenant de l??aurore?? in the ??Luxembourg?? French Senate building.
