Multi-channel signal recording with photoconductive antennas for THz imaging
Tóm tắt
We have constructed a small and cheap, yet efficient electronic circuit for reading out THz signals from photoconductive antennas. An 8-channel version of this circuit has been used for THz imaging by simultaneously recording sets of 8 time-domain THz waveforms with an array of 8 photoconductive antennas.
