摘要：

Heterodyne and spectroscopic terahertz imaging using InGaAs bow-tie diodes are presented and discussed. The improvement of the dynamic range and noise equivalent power by heterodyning is demonstrated. It is shown that InGaAs-based bow-tie diodes are well suited for spectroscopic room temperature imaging within the range of 0.58-2.52 THz. The devices implementation in real-time imaging system is considered as well.
