Observation of the thermal scene

  • Joseph Caniou


As with television cameras which operate in the visible spectrum, thermal imagers are used to form an image, i.e. a visual representation of the observed scene. In this type of application the properties of infrared radiation are used advantageously, particularly to improve visibility in bad weather or at night, e.g. for night-time driving of military vehicles and for surveillance of civil or military sites. The most elaborate systems comprise a digital data processing element. Sometimes the process, entirely automatic, sends an alarm or forms the link to a servomechanism providing target tracking.
