Embodiment Construction

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features...

Abstract

The present invention relates to the technical field of terahertz spectroscopy, and provides a terahertz spectrometer, including a dispersion compensation system for connecting with an external laser system, an optical beam splitter, an optical fiber stretching system for delay scanning the laser, and a It is a detection system for generating and receiving terahertz waves and detecting samples to be detected and a data processing system for analyzing test data. The dispersion compensation system is connected to an optical beam splitter through an optical fiber, and the optical beam splitter is simultaneously connected to an optical fiber through an optical fiber. The stretching system and the detection system are connected, the fiber stretching system is connected to the detection system through an optical fiber, and the detection system is connected to the data processing system through an optical fiber; because the laser is transmitted in the optical fiber, the stability of the terahertz spectrometer is effectively improved, making the terahertz The spectrometer can be applied to outdoor environments and industrial scenarios, effectively expanding the application scenarios of the terahertz spectrometer.

Description

technical field [0001] The present invention relates to the technical field of terahertz spectroscopy, and more specifically relates to a terahertz spectrometer. Background technique [0002] Terahertz waves refer to electromagnetic radiation with a frequency of 0.1-10 terahertz (Tera Hertz, THz) and a wavelength range of 0.03-30mm. be better utilized. Terahertz has a special position in the electromagnetic spectrum, resulting in many unique properties, which play an irreplaceable role in the development of new materials, semiconductors, life sciences and other fields. The terahertz band does not produce harmful ionizing radiation to biological tissues. Compared with visible light and infrared spectrum, it has stronger penetrating ability and is not easily affected by Rayleigh scattering. It can be used in biological imaging, medical diagnosis and other fields; terahertz Radiation has coherence, and can directly obtain the amplitude and phase information of the measured su...
