Abstract

The present invention discloses a mail detection device and method. The device comprises a broad-band terahertz generator, a collimator, a beam splitter, a fixed reflector, a movable reflector, a wave buncher, a matrix detector, an acquisition card and an information processing module; wherein the information processing module is used for generating a terahertz image of a mail to be detected according to the electric signals sent by the acquisition card when the movable reflector is motionless; and when finding suspicious articles according to the terahertz image of a mail to be detected, the information processing module controls the movable reflector to move, and generates spectral information of the suspicious articles according to an electric signal sequence sent by the acquisition card during the movement of the movable reflector.
