Paper Abstract

In recent years there have been rapid advances in infrared television cameras based upon metal-silicide focal plane arrays. These devices sense infrared via internal photo-emission of hot carriers a process that is analogous to vacuum photoemission. Internal photoemission is very reproducible and large arrays with cell to cell photoresponse uniformity better than 0.5% rms have been demonstrated. This uniformity has been exploited in the design of simplified cameras which require minimal pixel compensation. Projected applications of these cameras include medical diagnostics, reliability studies and infrared astronomy. The present paper will describe the development of the silicide camera technology, outline the physics of camera operation and demonstrate preliminary imagery in astronomy and thermal diagnostics.
