论文摘要
我们描述了1.2至10.5 THz之间的THZ光谱仪，该光谱仪由由Metasurfaces制成的带通滤波器组成。来源由10 W小的黑色身体制成。检测器是高灵敏度的室温pyroelectric传感器。描述了用于制备样品的各种技术。将获得的光谱与同一样品上用傅立叶变压器红外光谱仪测量的光谱进行了比较。该仪器使用目前可用的商业技术可以构成非常昂贵的光谱仪的经济替代方案。它已经成功使用，获得了许多无机粉末的精确光谱测量。
We describe a THz spectrometer operating between 1.2 and 10.5 THz, consisting of band pass filters made with metasurfaces. The source is made of 10 W small black body. The detector is a high sensitivity room temperature pyroelectric sensor. Various techniques used to prepare samples are described. The spectra obtained are compared with those measured with a Fourier Transformer Infrared Spectrometer on the same samples. The instrument, using commercial technologies available at the present time, can constitute an economical alternative to very expensive spectrometers. It has already been successfully used, getting precise spectroscopic measures of many inorganic powders.
