Abstract :
Physical principles of operation of the photodetecting devices based on the group III-doped IV-VI semiconductors are presented. We report on the performance of lead telluride-based single direct terahertz detectors. Architecture of a system for passive terahertz vision of room-temperature objects is presented.
