Document Type and Number:
WIPO Patent Application WO/2019/196202
Kind Code:
A1
Abstract:
A terahertz-based device (100) for detecting high-risk chemicals, the device comprising a terahertz wave generating unit (101), a terahertz wave transceiving unit (102) and an echo analysis unit (103); the terahertz wave generating unit (101) is used for generating a terahertz detection signal, a terahertz reference signal and a terahertz local oscillation signal; the terahertz wave transceiving unit (102) is used for transmitting the terahertz detection signal and the terahertz reference signal to a high-risk chemical to be detected, and receiving a terahertz echo signal carrying information of the high-risk chemical to be detected; and the echo analysis unit (103) is used for analyzing the terahertz echo signal and the terahertz local oscillation signal.
