Abstract

The invention provides a cage-structured fiber-based terahertz time-domain spectroscopy system provided with a waveguide test module. The system comprises a cage structure I, wherein the cage structure I comprises a cage structure I transmitting terminal and a cage structure I receiving terminal; a transmitting antenna, a transmitting terminal collimating lens and a transmitting terminal focusing lens are arranged on the cage structure I transmitting terminal sequentially; a receiving terminal collimating lens, a receiving terminal focusing lens and an exploring antenna are arranged on the cage structure I receiving terminal sequentially; a cage structure II is arranged between the cage structure I transmitting terminal and the cage structure I receiving terminal and comprises a cage structure II transmitting terminal connected with the cage structure I transmitting terminal and a cage structure II receiving terminal connected with the cage structure I receiving terminal, and the waveguide test module is arranged between the cage structure II transmitting terminal and the cage structure II receiving terminal. The waveguide test module is integrated in the cage structure of the fiber-based terahertz time-domain spectroscopy system, so that waveguides can be centered and aligned reliably and stably, and the system is stable in structure, convenient to adjust and test and high in reliability and integrity.

Description

technical field [0001] The invention belongs to the technical field of terahertz testing, and in particular relates to a cage structure fiber-based terahertz time-domain spectroscopy system with a waveguide testing module. Background technique [0002] Terahertz waves refer to electromagnetic waves with wavelengths between 3 mm and 30 μm and frequencies between 0.1 THz and 10 THz, between microwaves and infrared light waves. Because terahertz waves have the characteristics of low photon energy, high penetration, and relatively small loss during atmospheric transmission, terahertz technology has great potential in the fields of physics, biomedicine, material science, security inspection, military radar, imaging, and communications. Broad application prospects and great scientific value. The most widely used traditional terahertz spectrometer is terahertz time-domain spectroscopy. Through coherent detection, the terahertz time-domain pulse signal after passing the test sampl...
