We demonstrated fast terahertz spectral computed tomography by using real-time line projection of a terahertz beam. Two types of cross-sectional images of continuously rotating samples have been measured in only a few seconds. From temporal data, a peak-to-peak sinogram and cross sections have been reconstructed using a filtered backprojection algorithm. Using fast Fourier transform from temporal data, spectral cross sections of the sample have been obtained.
我们通过实时线投影太赫兹光束实现了快速太赫兹光谱层析成像。仅用几秒钟就测量了连续旋转样品的两种类型的横截面图像。从时间数据中，使用滤波反投影算法重建了峰峰值正弦图和横截面。从时间数据中使用快速傅里叶变换，获得了样品的光谱横截面。
