摘要
A continuous-wave all-optoelectronic terahertz imaging system based on diode lasers is presented. The coherent detection scheme is phase sensitive and operates at room temperature. This low-cost, compact system has image capture rates comparable with those from state-of-the-art pulsed THz systems.
