Problems solved by technology

[0004] However, the THz-TDS testing system in the prior art can only test the transmission spectrum or reflection spectrum of flat samples, and it is difficult to test bendable samples, especially some samples with adjustable curvature, such as some carbon fiber films, based on When a microstructured metamaterial sample is bent, its internal structure will undergo some changes, but the THz-TDS test system cannot be used to test this kind of sample

Abstract

The invention discloses a fixing device for a bendable sample based on a terahertz spectrometer. The fixing device comprises: a first clamp assembly and a second clamp assembly. The first clamp assembly at least comprises a first fixing clamp. The second clamp assembly at least comprises a second fixing clamp. The first fixing clamp and the second fixing clamp are arranged as follows: respectivelyclamping the first end and the second end of the to-be-detected sample, and the first fixing clamp and the second fixing clamp move in a first horizontal direction to bend the to-be-detected sample.In addition, the invention further discloses a measuring system comprising a terahertz time-domain spectrometer and the fixing device, and a measuring method. The measuring method adopts a measuring system for measurement, comprising the following steps of: clamping and fixing the to-be-measured sample by the fixing device; adjusting the bending degree of the to-be-measured sample according to needs; and emitting a terahertz signal by the transmitting end of the terahertz time-domain spectrometer, receiving the terahertz signal penetrating the to-be-measured sample by the receiving end of theterahertz time-domain spectrometer, and analyzing.

Description

technical field [0001] The invention relates to the field of terahertz application technology, and relates to a device, system and method for measuring using terahertz time-domain spectroscopy technology. Background technique [0002] Terahertz (THz for short) spectroscopy technology is one of the most important application directions in THz technology. Electromagnetic spectrum technology is an important tool for human beings to understand the world. It expands human beings' ability to observe the world. Through spectral technology, material molecules can be understood. It can also understand the structural information of matter, which plays a huge role in human understanding of the microscopic world. Therefore, THz technology is considered to be one of the top ten technologies that will change the future world. [0003] Terahertz time-domain spectroscopy (THz-TDS) technology is a typical representative of terahertz spectroscopy technology, and it is a very effective technol...
