我们展示了一种基于吸收对比度的深度分辨三维成像技术。断层合成类似于计算机断层摄影，除了投影的数量少得多。我们构建了一个断层合成成像系统，该系统检测透射的连续太赫兹波。我们采用了一种反投影方法，这是适合于所构建的检测配置，重建图像。使用这个系统，我们成像的测试样品由纸和复制的字符写的铅笔。
We demonstrated a depth-resolved 3D imaging technique based on absorption contrast using tomosynthesis. Tomosynthesis is similar to computed tomography except that the number of projections is much smaller. We constructed a tomosynthesis imaging system, which detects a transmitted continuous THz wave. We applied a backprojection method that was suitable for the constructed detection configuration, to reconstruct an image. Using this system, we imaged a test sample made from paper and reproduced characters written by pencil.
