Abstract
A terahertz gas spectrometer detection system is provided. The system includes: a terahertz generation module, a gas module, a terahertz detection module and a program-control and acquisition module. terahertz generation module is configured for generating and transmitting terahertz signals with different frequencies; gas module is configured for setting and storing to-be-detected gas, so that terahertz signals with different frequencies pass through the to-be-detected gas; terahertz detection module is configured for detecting amplitude signals of terahertz signals after passing through the to-be-detected gas through field effect transistor detector; program-control and acquisition module is configured for controlling the terahertz generation module to generate and transmit frequency of terahertz signal, and is further configured for acquiring amplitude detection signals of terahertz signals after passing through the to-be-detected gas, and generating spectrogram of to-be-detected gas.
