论文摘要
我们演示了一个单发的Terahertz光谱仪，该光谱仪由改良的Mach-Zehnder干涉仪和微量仪表型平面阵列组成。光谱仪易于使用，可以测量没有运动部件的Terahertz场自动相关和光谱功率，也没有超短型激光器。当用热源测试时，它可以有效地检测到10 $ \ sim $ 40 THz的辐射。它还可以用于测量样品材料的复杂折射率。原则上，它可以表征基于激光的和非激光的Terahertz来源，并可能覆盖1 $ \ sim $ 10 $ 10 thz，并具有特殊设计的Terahertz微型光度计。
We demonstrate a single-shot terahertz spectrometer consisting of a modified Mach-Zehnder interferometer and a microbolometer focal plane array. The spectrometer is simple to use and can measure terahertz field autocorrelations and spectral power with no moving parts and no ultrashort-pulsed laser. It can effectively detect radiation at 10$\sim$40 THz when tested with a thermal source. It can be also used to measure the complex refractive index of a sample material. In principle, it can characterize both laser-based and non-laser-based terahertz sources and potentially cover 1$\sim$10 THz with specially-designed terahertz microbolometers.
