Abstract

We have constructed a continuous-wave terahertz imaging system based on diode lasers, a photoconductive emitter, and a phase-sensitive photoconductive receiver. It is inexpensive and compact, but with a performance comparable with established pulsed terahertz systems. We also use a novel photonic crystal filter to remove unwanted low frequency noise components.

一种高性能的CW-THz光混像系统

我们构建了一个基于二极管激光器、光导发射器和相敏光导接收器的连续波太赫兹成像系统。它价格低廉，结构紧凑，但性能可与现有的脉冲太赫兹系统相媲美。我们还使用了一种新型的光子晶体滤波器来去除不需要的低频噪声成分。
