Abstract

A terahertz wave security inspection system (100) and a method thereof are provided. The terahertz wave security inspection system includes: an information acquisition device including a terahertz wave imaging mechanism (10) configured to generate a terahertz wave image of an object to be detected, and a visible light imaging mechanism (20) configured to generate a visible light image of the object to be detected, where the visible light image generated by the visible light imaging mechanism matches the terahertz wave image generated by the terahertz wave imaging mechanism within a range of depth of field of the terahertz wave imaging mechanism; and a data processing device (30) in data communication with the information acquisition device and configured to acquire the terahertz wave image of the object to be detected provided by the terahertz wave imaging mechanism and the visible light image provided by the visible light imaging mechanism, determine whether a suspected item exists in the object to be detected or not based on the terahertz wave image and the visible light image, and if it is determined that a suspected item exists in the object to be detected, determine whether the suspected item is a prohibited item or not based on the visible light image and the terahertz wave image.
