在过去的几十年里，辉光放电探测器（GDD）已被用于检测微波辐射。最近，这些探测器被用于研究电磁波谱的太赫兹（THz）波段内的更高频率。商业氖灯可以作为GDD，并在0.2太赫兹的性能进行了研究。搭建了基于GDD的THz连续波成像系统，并将GDD和肖特基二极管的成像结果进行了比较。实验结果表明，优化设计的GDD将是一个高效，快速，廉价的太赫兹成像系统的探测器。
In the last several decades, glow discharge detectors (GDD) have been utilized to detect microwave radiation. Recently, these detectors were used to study higher frequencies within the terahertz (THz) band of the electromagnetic spectrum. Commercial neon lamps can act as GDDs, and their performance at 0.2 THz was investigated. A THz continuous-wave imaging system with the GDD was constructed and the images obtained by the GDD and a Schottky diode were compared. The experimental results indicate that an optimally designed GDD will be an efficient, fast, and inexpensive detector for THz imaging systems.
