【摘要】：对文物的内部结构、缺陷、损伤等信息的检测是文物保护修复工作的基础和依据。目前普遍使用的X射线成像技术能量高、需要完善的防护条件,不仅限制了应用范围,而且对文物有一定安全隐患。红外热波成像技术是一种新型无损内部成像技术,是根据被检测物中缺陷处与正常处微小的热及热变化的不同来识别、判定缺陷的,可实现低能量、快速、非接触和原位检测,非常适合文物的检测分析。本文将主动式红外热波成像技术应用于故宫壁画、铸铁佛头、陶俑和汉白玉螭首等不同材质和类别文物内部结构的无损检测,得到了不同程度的文物内部结构信息,同时分析了该技术对多种文物的检测能力。结果表明红外热波无损检测技术可适用于多种材料和复杂结构的文物检测,提供文物内部缺陷和结构信息,为文物的保护与修复提供一种新的检测手段,具有广阔的发展前景。
[Abstract]:The detection of internal structure, defect and damage of cultural relic is the foundation and basis of preservation and restoration of cultural relic. The widely used X-ray imaging technology has high energy and needs perfect protective conditions, which not only limits the scope of application, but also has a certain safety hazard to cultural relics. Infrared thermal wave imaging is a new kind of non-destructive internal imaging technology, which is based on the difference between the defects in the detected object and the small thermal and thermal changes in the normal place to identify the defects, which can achieve low energy, fast, non-contact and in-situ detection. Very suitable for the detection and analysis of cultural relics. In this paper, the active infrared thermal wave imaging technology is applied to the nondestructive testing of the internal structures of different materials and categories of cultural relics, such as The Imperial Palace murals, cast iron Buddha heads, pottery figures and white chise-heads, and the internal structure information of cultural relics is obtained to different degrees. At the same time, the detection ability of this technology to various cultural relics is analyzed. The results show that the infrared thermal wave nondestructive testing technology can be applied to the detection of cultural relics of various materials and complex structures, and provides the internal defects and structural information of cultural relics, and provides a new testing method for the protection and restoration of cultural relics, and has a broad development prospect.
