摘　　要：太赫兹（THz）波具有非常宽的频谱，对大多数非金属材料（衣物、塑料、陶瓷等）具有穿透性，可实现三维成像。多种爆炸性物质分子的振动能级谱正好位于THz频段，通过THz光谱技术可以测得危险物品的特征吸收谱。根据THz波的特点及形成，可以将THz波光谱和成像技术用于危险品探测和安检领域。Terahertz （THz） wave spectrum is very wide, it can penetrate many non-metallic materials, such as clothing, plastic and ceramic, etc. , and it can also realize 3D imaging. Because the vibration and rotation energy spectra of many dangerous goods lie in the THz wave band, the characteristic absorption spectra of the explosives can be detected by the THz technology. The characteristic and the formation of the THz wave are introduced, and the applications of THz wave spectra and imaging technology in the field of dangerous goods detection and security are also discussed.
