Abstract: Terahertz (THz) imaging is one of the important directions for the application of THz technology. THz imaging systems based on semiconductor photonics devices such as THz quantum cascade lasers (QCLs) and THz quantum well photodetectors (QWPs) have the advantages of compact structure, high spatial resolution, and high imaging signal-to-noise ratio, and have become the research highlights in the related ﬁeld. In this paper, the research progress of far-ﬁeld and near-ﬁeld imaging systems based on THz QCL and THz QWP devices is systematically reviewed, the composition, mechanism, and performance of these THz imaging systems are carefully described, the performance parameters of each kind of imaging system are summarized, the methods to further improve the performance of THz imaging system are proposed and their application prospects are also discussed.

Key words: laser techniques, imaging, terahertz, quantum cascade laser, quantum well photodetector
