我们应用太赫兹时域光谱定量非侵入性评估生物样品中的水分含量，如鹅耳枥树叶和猪肉肌肉。所开发的实验太赫兹时域光谱系统工作在透射和反射模式。基于Landau-Looyenga-Lifshitz的模型用于计算样品中的水浓度。将水浓度测量的结果与重量测量的结果进行比较。所获得的结果表明，生物样品中的水含量可以测量非侵入性，具有高精度，利用太赫兹波的透射和反射模式。(c)根据OSA开放获取出版协议的条款，2018年美国光学学会。
We apply terahertz time-domain spectroscopy for the quantitative non-invasive assessment of the water content in biological samples, such as Carpinus caroliniana tree leaves and pork muscles. The developed experimental terahertz time-domain spectroscopy system operates both in transmission and reflection modes. The Landau-Looyenga-Lifshitz-based model is used for the calculation of the water concentration within the samples. The results of the water concentration measurements are compared with the results of the gravimetric measurements. The obtained results show that the water content in biological samples can be measured non-invasively, with a high accuracy, utilizing terahertz waves in transmission and reflection modes.
