摘要

本文实验建立了一种标准几何形状的脉冲太赫兹成像系统，并研究了在被覆盖的样品前放置针孔对成像质量的影响。并从理论上阐述了利用射线传递矩阵提高图像质量的方法。最后，利用轮廓系统对结果进行了评价，并对太赫兹成像系统的精度进行了测试。

THz non-destructive testing for covered defects

In this paper, a pulsed THz imaging system in normal geometry is presented experimentally and the effect of placing a pinhole in front of a covered sample on image quality has been investigated too. Also, the improvement of image quality by using ray transfer matrix is described theoretically. Finally, by using contour system the results are evaluated and the accuracy of THz imaging system is tested.
