We present a terahertz (THz) imaging technique based on attenuated internal reflection, which is ideally suited for the analysis of liquid and biological samples. Inserted in a THz time-domain system, and using a high-resistivity low loss silicon prism to couple the THz wave into the sample, the detection scheme is based on the relative differential spectral phase of two orthogonal polarizations. Biological sample imaging as well as subwavelength (λ/16) longitudinal resolution are demonstrated.
我们提出了一种基于衰减全内反射的太赫兹（THz）成像技术，该技术非常适合分析液体和生物样本。该技术将插入太赫兹时域系统中，并使用高阻低损耗硅棱镜将太赫兹波耦合到样品中，检测方案基于两个正交偏振的相对差分光谱相位。我们展示了生物样本成像以及亚波长（λ/16）纵向分辨率。
