In terms of frequency, it is between radio waves and light waves; in terms of wavelength, it is between millimeter waves and infrared waves; it is energetically intermediate between electrons and photons. In recent years, with the rapid development of the THz spectrum technology, the research and application of the THz frequency band at home and abroad are more and more. Among them, the field to which the THz spectroscopy can be applied is also becoming wider and wider.
According to research, the Terahertz time-domain spectroscopy (THz-TDS) has been increasingly applied to the fields of medicine, security inspection, material structure detection, transmission communication, biopharmaceutical and the like. The collective vibration of most biological macromolecules is in THz wave band, so that the THz time domain spectrum technology can be used for qualitatively judging substance elements and quantitatively testing substance content, and the terahertz absorption spectrum can determine conformation and configuration through specific characteristic spectrum; in addition, the terahertz wave has penetrability, can easily penetrate substances such as plastics and ceramics, can also detect biological tissue information under epidermis, has very low photon energy, cannot generate ionization effect like X-rays, has no damage to organisms and biological tissues, has very high sensitivity to polar substances, and has better contrast than X-rays in soft tissue tests. However, the application of THz time-domain spectroscopy techniques relies on the comparison of tests on the absorption coefficient of substances in the THz band.

However, the liquid phase substance has very rare introduction of the testing device due to the problems of fluidity, volatility, mixed heat dissipation and the like. In the prior art, liquid substance measurement is usually placed in a quartz cuvette, and the problems of large measurement error, difficulty in adjusting the measurement optical distance, low test efficiency and the like exist. In addition, when the liquid substance is repeatedly tested, the light path is influenced and the toxic liquid can cause damage to human body if careless. Therefore, it is important to design a testing device for the liquid phase substance in the THz wave band, which is rapid, safe, high in accuracy and easy to clean.
