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.

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.File in questo prodotto:
