As part of aid for the conservation of cultural heritage works of art, Infrared thermography is already widely used. However, the photothermal signal obtained can be dependent on the different colors of the pictorial layer of the artwork studied and on the inhomogeneity of energy deposition. In this work, we show experimentally, during the study of a marquetry chessboard and a "Vallauris pottery", that the combination of singular value decomposition with stimulated infrared thermography allows a significant reduction of these radiative effects. Consequently, it allows for better detection of the defects present in the works of art studied |
