连续波太赫兹反射成像是生物组织的潜在工具。基于自行研制的连续波太赫兹反射成像系统，从理论和实验两方面研究了偏振模式和反射窗口对成像性能的影响，两者吻合较好。考虑到获取样品信息和图像对比度，推荐使用p偏振太赫兹波。此外，考虑到样本边界识别和图像对比度，反射窗口的选择标准。该工作将有助于提高连续波太赫兹反射成像的性能，加速太赫兹成像在生物学中的应用。
Continuous‐wave terahertz reflection imaging is a potential tool for biological tissues. Based on our home‐made continuous‐wave terahertz reflection imaging system, the effect of both polarization mode and reflection window on the imaging performance is studied theoretically and experimentally, showing good agreement. By taking obtaining sample information and image contrast into consideration,p‐polarized terahertz waves are recommended. Moreover, considering the sample boundary identification and the image contrast, selection criteria for reflection window are proposed. This work will help to improve the performance of continuous‐wave terahertz reflection imaging and accelerate the THz imaging in biological application.
