This spectral feature can be exploited to detect the presence of water under the surface of mural paintings and mosaics. In this study we report on the capability of our 3D reflective THz imaging system to detect water under samples simulating a fresco or a mosaic.

Research paper thumbnail of An in situ non-invasive study of two Tibetan manuscripts from the Asian Collection of the Museum of Natural History in Florence

The historical value and fragility of these unique and priceless works of art, together with an increased awareness of the importance of preserving our cultural heritage, has prompted the use of non-invasive analytical techniques to the study of these ancient religious items. In particular, the present work aims to characterize inks and pigments of two ancient Tibetan manuscripts part of the collection of the Museum of Natural History, Department of Anthropology, in Florence (IT). A combination of portable microphotography, X-ray fluorescence (XRF), and UV-Vis-NIR fiber optic reflectance spectroscopy (FORS) was used for in situ investigation of all the most significant painted area appearing in the manuscripts. Information about the preparatory substrate, the pigments, and the metal inks were gained. A step forward a better understanding of the working methods applied by the artists was made, thus contributing significantly towards the planning of the most appropriate conservation-restoration procedures.

Hence, in order to accomplish a proper conservation program of these artefacts, it is fundamental the importance of studying the used dyes on historic textiles. Traditionally, the identification is carried out through invasive or micro-invasive techniques such as HPLC or Raman-SERS. However, a first screening using non-invasive approaches, that could tentatively identify some of the dyes in a contactless mode, is strongly reccommended. The present study focuses on the application of non-invasive spectroscopic techniques, namely FORS and hyperspectral imaging in the visible and near infrared range, for the identification of dyes on textiles. Twelve natural dyestuffs (twelve from plant, two insect dyes and a lichen) and three mordants (KAl(SO4)2, CuSO4 ∙ 5H2O, FeSO4 ∙ 7H2O) were selected and...

In the last few years a new interest was devoted to the longer wavelengths, in the so called “THz region” of the spectrum, due to the peculiar characteristics of the radiation in this spectral range, that make it ideal for applications in this field [1]: it's low photon energy and its ability to penetrate dielectric materials. This high penetration capabilities were used to demonstrate the possibility to detect artwork hidden under layers of other dielectric materials [2]–[4]. Making use of phase-sensitive techniques it is also possible to get information on the optical properties of the materials under study and to obtain images that include spectroscopic information about the sample [5]. Moreover, radiation in the THz range is strongly reflected and absorbed by water, and this feature can be used to study degradation in mural paintings and mosaics.
