Abstract
Viewing technology by infrared radiation, emitted and reflected, rivals that by low-light-level illumination, such as starlight. Parallel research and development in these fields have mainly been concentrated on instrumentation operating within the three atmos-pheric transmission "windows", the visible, mid and far infrared waveband regions of the electromagnetic spectrum. Both technologies have produced systems that have military and law enforcement applications but they are also being used for important peaceful applications; satellite surveillance for the Earth's resources, search and rescue; medical diagnoses, early warning machine breakdowns and the conservation of heat energy.
