论文摘要
在本文中，我们考虑了Terahertz（THZ）断层扫描的成像问题，尤其是在非破坏性测试中出现的。我们得出了一个非线性数学模型，描述了一个完整的THZ断层扫描实验，并考虑将THZ断层扫描与标准计算机断层扫描和ra晶变换连接起来的线性近似值。基于派生模型，我们提出了解决THZ断层扫描问题的不同重建方法，然后将其比较从塑料样品的THZ测量结果获得的实验数据。
In this paper, we consider the imaging problem of terahertz (THz) tomography, in particular as it appears in non-destructive testing. We derive a nonlinear mathematical model describing a full THz tomography experiment, and consider linear approximations connecting THz tomography with standard computerized tomography and the Radon transform. Based on the derived models we propose different reconstruction approaches for solving the THz tomography problem, which we then compare on experimental data obtained from THz measurements of a plastic sample.
