Terahertz (THz) time-domain spectroscopy was used in vivo to measure the body reflectance with the aim of determining experimentally the influence of haemodialysis on the content of water in the human skin. For this purpose, an original methodology of determining the skin properties at THz frequencies from the reflectance was developed. A series of measurements were performed before and after dialysis with ten subjects. The results strongly indicate that the surface body hydration is not the main parameter determining the skin conductivity in the THz range.
太赫兹（THz）时域光谱被用于活体测量人体反射率，目的是通过实验确定血液透析对人体皮肤水分含量的影响。为此，开发了一种从反射率确定太赫兹频率下皮肤特性的原始方法。对十名受试者在透析前后进行了一系列测量。结果有力地表明，体表水合作用不是决定太赫兹范围内皮肤电导率的主要参数。
