摘要
图像获取速率和空间分辨率一直是面向应用型太赫兹成像所要解决的关键问题。针对这一问题,学者们基于合成孔径雷达(SAR)成像技术、电磁干涉与压缩感知(CS)等理论,提出了太赫兹合成孔径成像、太赫兹干涉成像和太赫兹压缩感知成像技术,它们在成像速度和空间分辨率等方面具有良好的发展潜力。综述了上述三种方法,总结概括其各自的技术优势以及新近的研究进展。展望了太赫兹成像技术在军事、公共安全领域以及无损探伤等领域的应用前景。
The acquisition speed and spatial resolution are the key factors in application-oriented terahertz（THz） imaging systems.To solve this problem,the techniques of the THz synthetic aperture radar（SAR） imaging,THz interferometric imaging and THz compress sensing（CS） imaging have been proposed by scholars based on SAR,electromagnetic interference and CS.All of them have a good potential in imaging speed and spatial resolution.We review these techniques and summarize the technical advantages and recent research progress.The prospect of applications of THz imaging techniques in the fields of military,public safety and non-destructive defect identification is given.
