为了探索脂类有机大分子对太赫兹(THz)辐射的吸收特征，以及使用THz对生物有机大分子实现检测和鉴别，使用透射型太赫兹时域光谱(THz-TDS)系统获得了七种植物油、两种调和油的太赫兹吸收光谱，得到它们的特征吸收参数，对比和分析了它们特征吸收峰的差异。结果表明：脂类有机大分子对THz辐射具有差异性吸收，具备在THz波段的识别基础，可通过THz技术进行鉴别和定性分析。 To explore the characteristics of terahertz absorption spectra of lipid macromolecules, terahertz time-domain spectroscopy (THz-TDS) is applied to seven types of plant oils and two types of blend oils.

To explore the characteristics of terahertz absorption spectra of lipid macromolecules, terahertz time-domain spectroscopy (THz-TDS) is applied to seven types of plant oils and two types of blend oils. The oils are measured in the frequency range extending from 0 to 80 wavenumbers. The absorption features of the oils are different in such a frequency range, indicating that THz-TDS can be used to distinguish different types of oils, which is the basis for analyzing oil compos...
