Book excerpt: Infrared photodetectors are essential in many industries and modern applications require devices with enhanced capabilities. High-performance detectors can be used for spectroscopy in medicine and environmental monitoring. Imaging scenarios include the identification of military targets and predicting equipment failure. These thermal imaging systems benefit from multicolour photodetectors. For example, some heat-seeking missiles incorporate two-colour HgCdTe arrays to discern target aircraft from decoy flares. Hyperspectral imaging describes the fusion of imaging and spectroscopy. These systems exhibit high spatial and spectral resolution, generally by dispersing different wavelengths onto a focal-plane array. Agricultural surveys, extraterrestrial exploration and medical procedures can all benefit from this powerful technique.
