本文综述了基于非共线自由空间电光采样的二维太赫兹（THz）时空（2D-ST）成像及其在THz反射断层成像、THz光谱成像和THz光谱计算机断层成像（CT）中的应用。2D-ST THz成像能够以比以前高得多的速率进行高速图像采集。二维太赫兹反射层析成像是有效的可视化的内部结构的运动的油漆膜。太赫兹彩色扫描仪展示了快速无损检测移动药物片剂的潜力。提出了一种基于THz光束线投影的THz光谱CT系统，并将其应用于连续旋转物体的成像。2D-ST THz成像使得在各种实际应用中能够对运动物体进行功能性THz成像。
We review 2-D spatiotemporal (2D-ST) terahertz (THz) imaging based on noncollinear free-space electrooptic sampling and its application to THz reflection tomography, THz spectral imaging, and THz spectral computed tomography (CT). 2D-ST THz imaging enables high-speed image acquisition at much higher rates than previously. Two-dimensional THz reflection tomography was effective for visualizing the internal structure of a moving paint film. A THz color scanner demonstrated the potential of rapid nondestructive inspection of moving pharmaceutical tablets. A THz spectral CT system using real-time line projection of a THz beam was effectively applied to a continuously rotating object. 2D-ST THz imaging enables functional THz imaging of moving objects in various practical applications.
