High-Precision Terahertz Time-Domain Spectroscopy System For Fine Terahertz Spectrum Analysis, Pattern Recognition

         Profile

Terahertz Time-Domain Spectroscopy (THz-TDS) is an emerging, efficient and non-destructive detection technology based on terahertz waves. It is a typical representative of the application of terahertz technology. This technology is useful for studying the spectral characteristics of materials in the terahertz band , Analyzing the composition and structure of substances, and studying the vibration and rotation characteristics of molecules are of great value, and has been widely used in the fields of spectral analysis, biomedicine, safety testing, medical pharmacy, etc.

The QT-TS1000 high-precision terahertz time-domain spectroscopy system product is an all-fiber design, which has outstanding advantages in high-precision and long-delay; it can achieve a spectral width of more than 5THz and a spectral resolution capability of less than 2GHz, which is suitable for high-precision spectral measurement and analysis; Based on spectral data, abundant physical information such as the refractive index, absorption coefficient, extinction coefficient, and dielectric constant of the sample can be obtained at the same time, so as to realize sample composition analysis and quantitative measurement.

  High-Precision Terahertz Time-Domain Spectroscopy System Principle

This product is an all-fiber terahertz time-domain spectroscopy system. The fiber femtosecond laser emits two femtosecond lasers, one as the pump light source and the other as the detection light source. The pump light is transmitted to the transmitting antenna through the optical fiber, and a broadband terahertz wave is generated under the action of the bias voltage. The terahertz wave carries the information of the test sample by means of transmission or reflection and is received by the terahertz detector and passes through the spectrum Analytical techniques can obtain physical information such as the refractive index, absorption coefficient, and dielectric constant of the sample, which can then be used for qualitative and quantitative identification of substances.
