太赫兹（THz）光谱和太赫兹成像技术在艺术品的无损分析方面具有巨大的潜力。太赫兹波可以穿透不透明的材料，并且它们可以通过光谱成像非破坏性地执行三维材料映射。人们曾多次尝试对艺术品进行分析。许多机构已经取得了明确的成果，例如通过使用模型画来成像隐藏的艺术。我们成功地观察到乔托的蛋彩画杰作的第一个非侵入性横截面图像。这些结果证明了THz技术可以在艺术保护科学中获得有用的信息。(C)2010年科学院。由Elsevier Masson SAS出版。All rights reserved.
Terahertz (THz) spectroscopy and THz imaging techniques are expected to have great potential for carrying out the non-invasive analysis of artworks. THz waves can penetrate opaque materials and they can perform three-dimensional material mapping non-destructively by spectroscopic imaging. Several attempts have been made to analyse artworks. Clear results, such as imaging of hidden art by using model paintings, have been obtained by many institutions. We succeeded to observe the first ever non-invasive cross-sectional image of a tempera masterpiece by Giotto. These results prove that THz technology can yield useful information in art conservation science. (C) 2010 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
