Les couches picturales stratifiées: analyse et modélisation de l'aspect visuel

Abstract : A painting is a stratified medium, made of several pictorial layers. This research work aims at modelling the visual appearance of such diffusing media and at improving non destructive methods to identify the components used in works of art. The radiative transfer equation, solved by the auxiliary function method, allows the modelling of the visual appearance of these media. This modelling is validated by comparison with experimental diffuse reflectance spectra. The identification of pigments and dyes with a portable device has been extended to the recognition of the components of a pigment mixture. Moreover, the optical coherence tomography (OCT) developed during this work allows to image the pigments in pictorial layers and to obtain spectral information in order to identify their components.
