Abstract
Early attempts to extend staring-mode sensing into the thermal infrared spectrum failed, because the resulting imagery was dominated by spatial pattern noise. The source of this noise was modulation of the infrared background by local variations in sensor responsivity. In 1973, use of internal photoemission from silicide Schottky barrier arrays was proposed as a means of achieving the photoresponse uniformity necessary to obtain useful thermal imaging capability. In the next two year, silicide tube and solid state imaging devices were demonstrated. Tube development was abandoned in 1975. Solid state efforts were directed towards extension of photo-response to longer wavelengths and fabrication of large scale arrays with small, high fill factor, pixels. Cut-off wavelengths have evolved from 2 μm to 10 μm and array sizes from 1 x 64 to 512 x 512 since that time. Current silicide cameras have sensitivity comparable with the best scanning systems. This paper will describe recent advances in silicide sensors and project future technology trends.
