摘要
太赫兹(THz)成像是THz技术应用的重要方向之一。基于THz量子级联激光器(QCL)和THz量子阱探测器(QWP)等半导体光子学器件的THz成像系统具有结构紧凑、空间分辨率高、成像信噪比较高等优点,已成为当前研究的热点领域。对国内外关于THz QCL和THz QWP器件在远场和近场成像应用方面的研究进行了系统综述,分析了THz成像系统的构成和成像效果,总结了各THz成像系统的性能参数情况,并探讨了THz成像系统性能提升的途径及其应用前景。
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.
