Based on the phenomenon that the incident terahertz (THz) radiation can increase the discharge current and luminescent intensity of a glow discharge detector (GDD), the electrical and optical modes were used to detect the THz wave. The influence of GDD’s discharge current, orientation, size, phosphor coating, and polarization sensitivity were investigated in detail. The results show that the electron density, the receiving efficiency to THz wave and effectively collecting the output signals of GDD are important to improve the responsivity of GDD.

通过电和光模式使用辉光放电检测器进行太赫兹辐射检测

基于入射太赫兹（THz）辐射可以增加辉光放电探测器（GDD）的放电电流和发光强度的现象，采用电学和光学模式来检测太赫兹波。详细研究了 GDD 的放电电流、方向、尺寸、荧光粉涂层和极化灵敏度的影响。结果表明，电子密度、对太赫兹波的接收效率和有效收集GDD输出信号对于提高GDD的响应度具有重要意义。
