Forward Looking Infrared (FLIR)

  • Hand held or aircraft mounted device designed to detect heat differentials and display their images on a video screen. FLIRs have thermal resolution similar to IR line scanners, but their spatial resolution is substantially less; commonly used to detect hotspots and flareups obscured by smoke, evaluate the effectiveness of firing operations, or detect areas needing mopup.
