A terahertz continuous-wave transmission imaging system and its applications in security inspections are reported. A
Gunn oscillator is utilized as emitter and an unbiased Schottky diode is employed as detector in this system. The
sample is placed on an X-Y two-dimensional stage which is controlled by a computer. The intensity information of the
terahertz wave after passing though the sample is collected by the Schottky diode and fed into the computer.
Two-dimensional image is obtained by scanning the sample point by point. Compared with the terahertz pulse imaging
system, this system is compact, simple, and portable. Tennis bat with sheath and knife in the box are imaged by using
this system. The results obtained here show that this new technology can be widely used in security inspections.
