Abstract

The conservation of painted panel supports is a fundamental aim of the whole restoration process. The measurement method up to now utilized by Opificio is based on the application on the panel of reference points, through which a centesimal gauge measures positive and negative movements. We propose a measurement method based on fiber Bragg grating (FBG) sensors. An array of Bragg gratings was glued on several crucial points of the wood structure, and the data were continuously collected. A set of measurements were performed in order to study the deformations of a painted wood panel, induced by relative humidity changes.
