Terahertz time-domain spectroscopy (THz-TDS) technology is a typical representative of the application of terahertz technology. Its technology is relatively mature and has a wide range of application scenarios.
The company's products are all-fiber terahertz time-domain spectroscopy systems. Fiber-optic femtosecond lasers emit two femtosecond lasers, one as a pump light source and the other as a detection light source;
The pump light is transmitted to the transmitting antenna through the optical fiber, which generates a broadband terahertz wave under the action of a bias voltage.
The terahertz wave carries the information of the test sample through transmission or reflection and is received by the terahertz detector.
Spectral analysis technology can be used to obtain physical information such as the refractive index, absorption coefficient, and dielectric constant of the sample, and then the qualitative and quantitative identification of the substance can be performed.
