Vers des techniques de contrôle pour la conservation des panneaux de bois peints

(Text in French) Towards control techniques for the conservation of painted wooden panels. Wood is a hydrophilic material, and wooden panels, which were very common before the advent of easel painting, are sensitive to the changes in humidity that occur in museums, whether in the exhibition hall or in storage. While preventive conservation approaches mostly involve controlling sudden changes in temperature and humidity, it is now possible to monitor the effects of these changes directly on the objects themselves. This article presents an experimental approach to assessing the impact of climatic variations based on actual measurements of humidity and temperature. The results show the real potential of digital holography speckle pattern interferometry (DHSPI) as a measurement and monitoring tool for this type of issue.
