Parent topics

• Infrared light [r]: In physics and engineering, a non-visible portion of the electromagnetic spectrum ranging from wavelengths of 750 nm to 1 mm, between the darkest visible red and the shortest submillimeter wave radar ^[e]
• Heat [r]: A form of energy that flows spontaneously from hotter to colder bodies that are in thermal contact. ^[e]
• Remote sensing [r]: Add brief definition or description
• Spectrometry [r]: Spectroscopy is the study of interaction of electromagnetic radiation with matter in those cases where the interaction causes transitions between the allowed states of matter. Spectrometry is the quantitative measurement of spectroscopic signal amplitudes. Light scattering also involves interaction of electromagnetic radiation with matter, however, in light scattering the energy of the electromagnetic field is NOT absorbed by matter (it is scattered). ^[e]

Subtopics

• Forward-looking infrared [r]: Add brief definition or description
• Thermal imaging [r]: Electro-optical techniques, operating in the infrared spectra, which form human-recognizable images; distinguished from infrared spectrometry that measures infrared energy on a point-by-point basis in the field of view but does not form an image ^[e]
• Infrared guidance [r]: Add brief definition or description

Detectors

• Mercury cadmium telluride [r]: (MCT or HgCdTe) A semiconductor used for infrared light detection, which can be adjusted, in manufacturing, to cover different parts of the infrared band; operated as a thermoelectrically or liquid nitrogen cooled device ^[e]
• Lead sulfide [r]: (PbS) Naturally occurring as galena, an important ore of lead, it also is used as an infrared light detector optimized for operation in the 1-3.5µm near IR band ^[e]
• Lead selenide [r]: (PbSe) photoconductive infrared detectors designed for operation in the 2-6 µm wavelength range, with peak response approximately 4 to 4.7 µm ^[e]
• Indium gallium arsenide [r]: (InGaAs) Semiconductor substrate for infrared light detectors in the 700nm to 1.8µm near infrared band ^[e]

Other related topics

• Electro-optical MASINT [r]: Add brief definition or description
• Electro-optical tracking [r]: The use of electronics, possibly in combination with mechanical positioning systems, to aim an optical system at a source of infrared, visible, or ultraviolet light, and follow it for purposes of observation or weapons guidance ^[e]

Articles related by keyphrases (Bot populated)

• CH-54 [r]: A Vietnam War-era heavy cargo helicopter that had no passenger cabin, in the interest of giving it more capability to carry externally slung loads ^[e]
• Joint Special Operations Command [r]: A major subordinate unit of the U.S. Special Operations Command, which takes on the most sensitive covert military operations, usually working unacknowledged within the geographic area of a Unified Combatant Command ^[e]
• Pain [r]: Unpleasant feeling or hurtful sensation that is conveyed to the brain by stimulation of sensory neurons. ^[e]
