摘要： Disclosed herein are a system and corresponding method for sensing terahertz radiation. The system collects terahertz radiation scattered from a target and upconverts the collected radiation to optical frequencies. A frequency-domain spectrometer senses spectral components of the upconverted signal in parallel to produce a spectroscopic measurement of the entire band of interest in a single shot. Because the sensing system can do single-shot measurements, it can sense moving targets, unlike sensing systems that use serial detection, which can only be used to sense stationary objects. As a result, the sensing systems and methods disclosed herein may be used for real-time imaging, including detection of concealed weapons, medical imaging, and hyperspectral imaging.

摘要翻译： 这里公开了用于感测太赫兹辐射的系统和相应的方法。 该系统收集从目标散射的太赫兹辐射，并将收集的辐射上变频到光频率。 频域光谱仪平行地感测上转换信号的光谱分量，以在单次拍摄中产生整个感兴趣的频带的光谱测量。 因为感测系统可以进行单次测量，所以它可以感测移动目标，不同于使用串行检测的传感系统，只能用于感测静止物体。 结果，本文公开的感测系统和方法可用于实时成像，包括隐藏武器的检测，医学成像和高光谱成像。
