Terahertz gas detection method and device based on gregory double reflection antenna

Abstract

The present disclosure relates to a terahertz-based high-risk chemical detecting device, which includes a terahertz wave generating unit, a terahertz wave transmitting and receiving unit and an echo analysis unit. The terahertz wave generating unit is configured for generating a terahertz detection signal, a terahertz reference signal and a terahertz local oscillation signal. The terahertz wave transceiver unit is configured to transmit the terahertz detection signal and the terahertz reference signal to a high-risk chemical to be tested, and receive information about carrying a high-risk chemical to be tested. The terahertz echo signal is configured to analyze the terahertz echo signal and the terahertz local oscillation signal to obtain information about a high-risk chemical to be tested. The present disclosure also relates to a terahertz-based high-risk chemical detecting method.
