Detection in the Terahertz Range. Part 1
The paper discusses the problems associated with the development of technology for detectors of terahertz radiation. The main physical phenomena and recent progress in various methods of detecting terahertz radiation (direct detection and heterodyne detection) are considered. The advantages and disadvantages of direct detection sensors and sensors with heterodyne detection are discussed. In the first part, a number of features of direct detection are considered and a description of some types of terahertz detectors of direct detection is given.
