Forward-Looking Infrared

Forward Looking InfraRed (FLIR) cameras flown from fixed-wing aircraft measure the amount of energy radiated in the infrared (7.5 - 13 micrometer) to detect detailed information on the land surface temperature distribution that might indicate areas of geothermal activity.[1]

Wikipedia Definition

Forward looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation.The sensors installed in forward-looking infrared cameras—as well as those of other thermal imaging cameras—use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create a "picture" assembled for video output.They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm)., Forward looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation.The sensors installed in forward-looking infrared cameras—as well as those of other thermal imaging cameras—use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create an image assembled for video output.They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background.
