Abstract
Radiation detectors that work at mid-infrared and longer wavelengths have many applications, including night vision, navigation, weather monitoring, flight control and early warning radars. The absorption lines of many gas molecules – such as ozone, water, carbon monoxide and nitrous oxide – occur at these wavelengths (between 3 and 18 μm), so infrared detectors can be used to monitor pollution, humidity and the distribution of different molecular species in the atmosphere.Keywords
