Non-destructive portable techniques for the analysis of cultural heritage items are essential for enhancing our understanding of these objects and providing valuable information for potential restoration interventions. This paper presents a combined use of pulsed thermography, X-ray fluorescence, and Raman spectroscopy to investigate the ancient bronze "Il Togato", yielding complementary information concerning the techniques used for creating this artefact and its conservation status. Specifically, thermographic analysis has highlighted the presence of many patches of different size used for emending superficial cast defects, weldings used to connect parts separately cast to the main structure, cracks, and defects located in the bronze thickness. On the other hand, XRF provided information on the composition of the gilding which characterises the statue, and supplied an estimate of its thickness through the use of a stratification model. Additionally, Raman spectroscopy has been applied to identify corrosion products. The experimental results presented in the paper provide a comprehensive knowledge of the bronze under investigation and assess the effectiveness of the portable non-destructive techniques employed in the analysis.
用于文化遗产物品分析的无损便携式技术对于增进我们对这些物品的理解以及为潜在的修复干预提供有价值的信息至关重要。本文介绍了脉冲热成像、X射线荧光和拉曼光谱的联合使用，以研究古代青铜雕像“Il Togato”，从而获得有关制造该文物所使用的技术及其保存状况的补充信息。具体而言，热成像分析突出显示了用于修补表面铸造缺陷的许多不同尺寸的补丁、用于将单独铸造的部件连接到主体结构的焊接、裂缝以及位于青铜厚度中的缺陷。另一方面，X射线荧光提供了有关表征该雕像的镀金成分的信息，并通过使用分层模型估算了其厚度。此外，拉曼光谱已应用于识别腐蚀产物。本文给出的实验结果提供了对所研究青铜的全面了解，并评估了分析中所采用的便携式无损技术的有效性。
