We demonstrate terahertz (THz) imaging with a quasi-time-domain spectrometer. This type of THz system is inexpensive, compact, and relatively easy to set up. Beating the simultaneously emitted equidistant modes of a compact diode laser allows for analysis of samples at multiple frequencies with a single measurement. Thus, this technique merges the potential of terahertz time-domain spectrometers with the simplicity of continuous wave lasers. Multiple imaging applications and stability issues are discussed.
我们展示了使用准时域光谱仪进行太赫兹（THz）成像。这种类型的太赫兹系统价格低廉、体积紧凑，并且相对易于设置。对紧凑型二极管激光器同时发射的等距模式进行拍频，能够通过单次测量对多个频率的样品进行分析。因此，这项技术将太赫兹时域光谱仪的潜力与连续波激光器的简易性结合在一起。文中还讨论了多种成像应用和稳定性问题。
