太赫兹衰减全反射成像已被用于开发初步的应用程序，没有任何深入的分析，目前的系统的性质。基于我们提出的垂直扫描成像系统，从理论和实验上分析了最佳棱镜设计和偏振选择对减小误差的影响。考虑到棱镜内部的二次反射和棱镜偏转，p偏振太赫兹波推荐用于底角小于31°的棱镜，以使误差最小。该工作将有助于太赫兹衰减全反射扫描成像在各个领域的实际应用，并提高其性能。
Terahertz attenuated total reflection imaging has been used to develop preliminary applications without any in-depth analysis of the nature of present systems. Based on our proposed vertically scanning imaging system, an analysis of optimum prism design and polarization selection for error reduction is presented theoretically and experimentally, showing good agreement. By taking the secondary reflection inside the prism and the prism deflection into consideration, p-polarized terahertz waves are recommended for prisms with a base angle below 31°, leading to minimum error. This work will contribute to the development of more practical application of terahertz attenuated total reflection scanning imaging in various fields with enhanced performance.
