摘　　要：采用1.89 THz的连续太赫兹波作为光源,124×124像素的热释电相机作为探测器,论证两种加入及未加入分光片的简易太赫兹反射成像装置.为评估这两套系统的性能,分别利用其对一枚人民币5角硬币进行成像.实验结果表明,与没有插入分光片的系统相比,插入分光片的系统可解决成像畸变问题,成像质量较高.By using 1.89 THz continuous terahertz wave and a 124 × 124 element pyroeleetric camera, two compact imaging configurations were demonstrated in reflective geometry with and without a beam splitter. A Chinese 50-cent coin was tested with the aim to evaluating the performance of these two systems. Compared to the system without a beam splitter, the system with a beam splitter can solve distortion problems. The resulting image is of high quality, evidenced by the clearer image of the numeral ＂5＂ with several dim Chinese characters around it without any distortion.
