Terahertz imaging with antenna coupled detectors

Practical cost effective implementations of imaging systems operating at terahertz frequencies are currently not available. Specifically, imaging at terahertz frequencies still requires advances in technologies such as detectors and sources and imaging techniques to make applications that use these frequencies a reality. This paper discusses work which is advancing knowledge in the terahertz area through development of antenna coupled detectors with an emphasis on their properties in an imaging system.
