Infrared/THz detector systems, optical components and instrumentation

We review commonly used cooled detector technologies along with associated cooling systems and optical components. Our current developments are discussed which we hope will lead to a wider use of sensitive detector technologies and systems in a new generation of IR/THz "field" applications. We look forward to a cryogen-free THz camera with high sensitivity and speed of detection which, with remote control capability would be a powerful diagnostic tool.
