红外技术在文物科学保护中的应用

无损检测是文物科学保护中的重要内容之一，而其中红外技术因其非接触、非破坏、高效率、适用性广、安全性好等诸多优势而得到普遍应用。在简要介绍红外技术相关原理和特点的基础上，综述了红外摄像、红外光谱和红外热成像应用于该领域所取得的最新成果，发现不同技术在表征文物影像特征、内部结构以及物理化学性质方面各有成效。红外技术能够挖掘各种类型文物的价值、工艺、病害和修复历史等隐藏信息，为其科学认知和保护提供定性甚至定量参考依据，因此表现出广阔的应用前景。

Application of infrared technique for scientific conservation of cultural relics

Non-destructive testing is one of the important aspects in scientific conservation of cultural relics, where infrared technique has been extensively adopted due to many advantages such as non-intact, non-destructive, high efficiency, wide applicability and safety. A brief introduction about the theory and characteristics of infrared technique is given. By reviewing the latest achievements obtained by infrared photography, infrared spectroscopy and infrared thermography, it shows that infrared technique is very effective in characterizing the image features, internal structures as well as physical and chemical properties of cultural relics. Infrared technique can not only reveal the hidden information about value, technology, pathology and repair history of various types of cultural relics, but also provide qualitative even quantitative reference for their scientific recognition and conservation, which displays a wide prospect in application.
