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.
採用1.89 THz的連續太赫玆波作為光源,124×124像素的熱釋電相機作為探測器,論證兩種加入及未加入分光片的簡易太赫玆反射成像裝置.為評估這兩套繫統的性能,分彆利用其對一枚人民幣5角硬幣進行成像.實驗結果錶明,與沒有插入分光片的繫統相比,插入分光片的繫統可解決成像畸變問題,成像質量較高.

By using 1.89 THz continuous terahertz wave and a 124×124 element pyroelectric 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.
