Abstract
This paper describes the design, implementation and measurements of a detector for imaging purposes at terahertz frequencies. The detector comprises of a ring slot antenna coupled to a high temperature superconducting Josephson Junction device. The detector was shown to respond to an incident field at 0.6 THz. An imaging system was constructed to test the detector's ability to generate images at 0.6 THz. Images have been acquired that demonstrate the ability of the detector to operate in an imaging mode in scenarios that exploit terahertz radiation's unique properties including penetration through packaging, sensitivity of water and millimeter scale resolution.
