The FLIR Advantage- Vertical Integration Silicon ROIC Focal Plane Array (FPA) Cooled or Uncooled Detector Dewar/Cooler Assembly (DDCA) Optical Imaging Engine Thermal Imager Detector (MEMS or III-V Compound) Thermal System Detector Package and Cooler/Stabilizer (TEC or Stirling Cooler), (Hi-Vac, Low-Vac, or Backfilled Package) Electronics Final Packaging Enclosure, App Software, UI
Thermal/Visible Sensor Integration Detect Complementary technologies Identify
Very Near Infrared (Far Visible) Gamma Rays 0.7um – 1.0um 10-4nm Mid Infrared 3um – 5.5um X-Rays Long Infrared 5.5um – 14um 1nm Ultra Violet Visible 1um Infrared Microwaves 1mm Radio 1m Uncooled Thermal Cameras • High solar rejection • High penetration of smoke and many fogs • MEMS-based, uncooled silicon detectors work well • Lowest cost thermal technology Dr. Richards Uncooled VOX Sensor Dr. Richards Cooled InSb Sensor
Typically used for ranges < 2-3km Ideal for terrain-limited installations Ideal for border crossing walk-arounds Short/Medium Range Uncooled Cameras Multi-Sensor – Dual thermal cameras & day/night zoom on pan-tilt Thermal Only
Industry Trend Rapid Migration to 640x480 sensors Mid Format Detectors Large Format Detectors 320 x 240 Pixels 640 x 480 Pixels Having only 76,800 pixels to capture information about the scene. Having 307,200 pixels to capture information about the scene. What does this mean? 4x the resolution of mid format arrays. More pixels means better image quality, creating greater detection capability than mid format sensors, which has created the move to high definition.
Industry Trend Advanced Signal Processing Yields Higher Performance – A digital, thermal image has more information in it than is obvious to the “naked” eye. The detector can sense differences to 0.03°C – Digital image processing allows us to apply dynamic, regional contrast settings to enhance human visual interpretation of events. Without DDE With DDE
