Abstract

Terahertz imaging is unlocking unique capabilities for the analysis of cultural heritage artifacts. This paper uses terahertz time-domain imaging for the study of a gilded wooden artifact, providing a means to perform stratigraphic analysis, yielding information about the composition of the artifact, presence of certain materials identifiable through their THz spectral fingerprint, as well as alterations that have been performed over time. Due to the limited information that is available for many historic artifacts, the data that can be obtained through the presented technique can guide proper stewardship of the artifact, informing its long-term preservation.

摘要

太赫兹成像正在为文化遗产文物分析开启独特的能力。本文利用太赫兹时域成像技术对一件镀金木质文物进行研究，提供了一种进行地层分析的方法，能得出有关该文物组成、可通过其太赫兹光谱指纹识别的某些材料的存在情况以及随时间发生的变化等信息。由于许多历史文物可用信息有限，通过本文所介绍技术获取的数据能够指导对文物的妥善管理，为其长期保存提供依据。
