Infrared Radiation can see through smoke, fog, and plastic. It was discovered in 1800 by Sir William Herschel. All objects emit infrared radiation, with hotter objects emitting more and cooler objects emitting less. Infrared light has a wavelength between 8 and 12 microns. Infrared light past 1400nm is absorbed by the vitreous humor and the lens of the eye, therefore optical beams in this region can carry more power than visible beams.
[[Electro-Optical Seeker]] – typically uses IR
[[Discovery of IR Radiation]] –
[[Second Harmonic Generation]] – used to convert infrared laser light into green light
[[Optical Communication]] – can use infrared beams with greater power than visible beams
Fiber Optic Networks – use infrared light
[[AMG8833]] – senses between 5-12 microns
