forward looking infrared

...Then, in the 1950s, technology was developed to electronically increase the brightness of images by tens of thousands of times, leading to the appearance of the Starlightscope (low-light night vision device), which allows one to see objects by starlight. Objects emit weak infrared light even in the dark, and the technology to see this infrared light improved, leading to the appearance in the United States of the FLIR (forward looking infrared) around 1968, a device that can observe objects at long distances without any lighting. Various night vision devices like these are already in practical use in various countries, making it possible to aim various firearms in the dark, monitor battlefields, control vehicles, and take off and land helicopters, dramatically changing the traditional form of night combat. ...

…その後50年代に，像の明るさを電子的に数万倍に増強する技術が開発され，星明りで物を見るスターライトスコープ(微光暗視装置)が出現した。物体は暗闇でも微弱な赤外線を発しているが，この赤外線を視認する技術が進歩し，68年ごろ，まったく照明なしに遠距離の物体も観測できる装置，FLIR(forward looking infrared)がアメリカで出現した。このような各種暗視装置は各国ですでに実用化され，暗闇における各種火器の照準，戦場監視，車両操縦，ヘリコプターの離着陸を可能にし，従来の夜間戦闘形態を大幅に変えた。…
