So we can take these measurements and pass them into a reconstruction algorithm to then recover the 3D geometry of this hidden scene.
所以我们可以进行这些测量并将它们传递给重建算法，然后恢复这个隐藏场景的 3D 几何形状。

Reconstruction algorithm
In tomography, a variety of practical reconstruction algorithms have been developed to implement the process of reconstruction of a 3-dimensional object from its projections. These algorithms are designed largely based on the mathematics of the Radon transform, statistical knowledge of the data acquisition process and geometry of the data imaging system.
