infrared film

Film carrying an emulsion especially sensitive to “near infrared.” The film is used for tasks such as camouflage detection to distinguish between living vegetation and dead vegetation or artificial green pigment. The film also is used to photograph objects through haze because of the penetrating power of infrared light. Infrared film can also distinguish between aircraft that has no fuel in it and that which is fueled, as the latter will be cooler than the former and this will show up in the film. See also near infrared.
