Fifty years of HgCdTe detectors: A video interview with Tom Elliott

From explosions to obscurity, Tom Elliott discusses the history of this important technology.
9 June 2009, SPIE Newsroom. DOI: 10.1117/2.3200906.01

A two-day celebration of the 50th anniversary of mercury-cadmium-telluride (HgCdTe; or MCT) detector technology took place at the SPIE Defense, Security and Sensing symposium in April 2009, in the conference on Infrared Technology and Applications. Chair Paul Norton, U.S. Army Night Vision and Electronic Sensors Directorate, introduced the program with a talk by Tom Elliott, inventor of the SPRITE detector and early leader of the development and application of the technology. Elliott developed the detector at what was then the Royal Research Establishment, later known as Defence Establishment for Research, Malvern, and now QinteQ.

Later, Elliott was interviewed by Ron Scotti for SPIE Newsroom after his presentation at the meeting.
