dc.description.abstractEnIn this paper, we present the potential of Terahertz Time-Domain Imaging (THz-TDI) as a tool to perform non-invasive 3D analysis of an ancient enamel plate made by Longwy Company in France. The THz data collected in the reflection mode were processed using noise filtering procedures and an advanced imaging approach. The results validate the capability to identify glaze layers and the thickness of ceramic materials. To characterize the nature of the pigments, we also go with X-ray images, visible near-infrared hyperspectral imaging spectroscopy, and p-XRF (portable X-ray fluorescence) to qualitatively and quantitively identify the materials used. The information obtained made it possible to better understand the nature of the decoration chromogens and, thus, to determine the color palette of the artists who produced this type of decorative object. We also establish the efficiency of a focus, Z-tracker, which makes it possible to perform THz imaging on non-flat samples and to attenuate artifacts obtained with a short focus lens. Then, 3D images are extracted and generated, providing a real vision of the 3D object. We also report the evaluation of the internal damage state based on the detection of fractures.
