Why did "forward looking" get glued onto that acronym? Why not just IR camera or detector? Did the military have less popular rear or side looking infrared devices? maybe "FLIR" was just fun to say? On a rocket powered missile rear-looking infrared seems pretty useless.
- alexhutcheson 8y agoYes, early infrared imaging systems were "push broom"[1] scanners facing perpendicular to the direction of travel. Forward-looking sensors required some additional tech to be developed: https://en.wikipedia.org/wiki/Forward-looking_infrared#Origin_of_the_term https://en.wikipedia.org/wiki/Forward-looking_infrared#Origi... FLIR is arguably a misnomer when applied to handheld devices, though. [1] https://en.wikipedia.org/wiki/Push_broom_scanner https://en.wikipedia.org/wiki/Push_broom_scanner
