Terahertz (THz) radiation has the characteristics of penetrating nonmetallic and nonpolar materials that are opaque to visible light, which makes THz digital holography have an application potential of imaging concealed objects with certain barriers. A CO(2) pumped continuous THz Gabor inline digital holographic imaging system was utilized to conduct experimental researches on imaging concealed objects. Paper, Teflon, a plastic express envelope, and silicon wafers were used as barriers. High-quality reconstructed images were obtained. Compared with the reconstruction results without any barriers, the results verify the feasibility of THz Gabor inline digital holography in imaging concealed objects.
太赫兹（THz）辐射具有穿透对可见光不透明的非金属和非极性材料的特性，这使得太赫兹数字全息术在对具有一定障碍物的隐藏物体进行成像方面具有应用潜力。利用一台二氧化碳泵浦的连续太赫兹加博尔同轴数字全息成像系统对隐藏物体成像进行了实验研究。使用纸张、特氟龙、塑料快递信封和硅片作为障碍物。获得了高质量的重建图像。与无任何障碍物时的重建结果相比，这些结果验证了太赫兹加博尔同轴数字全息术对隐藏物体成像的可行性。
