| 摘 要： | 采用太赫兹时域光谱技术对传统中国壁画的部分制作流程进行了分析，获得了壁画制作每个流程的太赫兹时域反射谱。研究了传统中国壁画在0.2～1.0 THz频率范围内的太赫兹光谱特性，得到了其在室温环境下的太赫兹吸收谱和折射率。结果表明，各样品的折射率平均值和吸收系数的峰值频率差异显著。研究结果能为太赫兹时域光谱技术在壁画信息提取领域的应用提供参考。

| Abstract: | By using terahertz (THz) time-domain spectroscopy to analyze part production processes of traditional Chinese murals, the THz time-domain reflection spectra of each mural production process are obtained. The THz spectral characteristics of traditional Chinese murals in the frequency range from 0.2 THz to 1.0 THz are studied. The THz absorption spectra and refractive index of traditional Chinese murals at room temperature are obtained. The result shows that there is a remarkable difference in the mean refractive index and peak absorption coefficient frequency for each sample. It can provide the reference for the application of THz time-domain spectroscopy in mural information extraction. |
