Abstract
We developed a security passengers gate using by terahertz-wave screening system. The security gate was based on a gas sensing system with an injection-seeded terahertz-wave parametric generator and was demonstrated with methanol gas in atmosphere detected as a phantom. The measurement was done within one second without disrupting foot traffic.
