Abstract :
Infrared detectors (3-20 μm) are important due to three main reasons. Firstly, the atmosphere is transparent in the two bands referred to as mid wave infrared (MWIR, 3-5 μm) and long wave infrared (8-12 μm) making it possible to see through fog and smoke under poor visibility conditions. Secondly, a lot of chemical species have characteristic absorption features in this wavelength range making these detectors vital for remote sensing and stand off detection. Finally, there is blackbody emission from living objects at these wavelengths making it possible to use them for “night vision” and thermography applications such as surveillance and medical diagnostics.
