Abstract

The invention relates to the technical field of terahertz spectroscopy, and provides a terahertz time-domain spectrometer. The terahertz time-domain spectrometer comprises a spectrometer main body, asample bearing structure and a scanning driving device, wherein the spectrometer main body includes a terahertz generator and an installation cooperation structure, the installation cooperation structure is detachably connected with a reflection imaging device/a transmission spectrum testing device, the sample bearing structure has a scanning operation position and a scanning operation-waiting position, the scanning driving device is used for driving the sample bearing structure to move between the scanning operation position and the scanning operation-waiting position in a reciprocating modeand used for driving the sample bearing structure to carry out a scanning operation when the sample bearing structure is at the scanning operation position. The terahertz time-domain spectrometer changes the test mode without a need of frequently assembling, disassembling and debugging a scanning imaging test device, the test device can be replaced quickly and conveniently without optical alignment, and diversified test requirements of users can be met.

Description

technical field [0001] The invention relates to the technical field of terahertz spectroscopy, in particular to a terahertz time-domain spectrometer. Background technique [0002] Terahertz time-domain spectroscopy technology is a new and very effective electromagnetic radiation phase coherent detection technology in terahertz spectroscopy technology. Qualitative analysis of samples has been widely used in biomedicine, chemistry, agriculture, medicine, pharmaceuticals, materials, food, drug testing and other fields. [0003] In actual application, according to different samples and test requirements, different test devices such as scanning imaging test devices and transmission spectrum test devices can be connected to the host of the terahertz time-domain spectrometer to obtain test data of the samples. Among them, Scanning imaging and spectral line testing are more commonly used testing methods. However, when the traditional terahertz time-domain spectrometer performs sca...
