This paper presents a study carried out on the painted altarpiece preserved inside the Basilica of Santa Maria in Cosmedin, Rome, by combining three imaging techniques operating in the near- and mid-infrared spectral ranges. The altarpiece has several pictorial layers and restorations, which have superimposed over time for stylistic adjustment and conservative purposes up to its present appearance. The results obtained in this study enable the detection of damage to the wooden support and the identification of pictorial features buried beneath the visible paint layer, thus providing significant information on the historical and artistic characterization of the artefact.

结合使用红外成像技术研究 Cosmedin 祭坛画中圣玛丽亚的潜在特征

本文通过结合在近红外和中红外光谱范围内操作的三种成像技术，对保存在罗马科斯梅丁圣玛丽亚大教堂内的彩绘祭坛进行了一项研究。祭坛画有几个图案层和修复体，随着时间的推移，为了风格调整和保守目的而叠加，直到现在的外观。本研究中获得的结果能够检测木质支架的损坏并识别隐藏在可见油漆层下方的图形特征，从而提供有关文物的历史和艺术特征的重要信息。
