3 Course Description Surveillance cameras are specified for daytime and/or nighttime performance. Proper specification and application involves a basic understanding of the performance differences between thermal and visible cameras. These performance levels are mainly determined by the imager (chip) technology employed in the camera. This course provides fundamental knowledge of each type of imager technology, their application, and current and future developments 3 Professional Education for the Security Industry

4 Learning Objectives At the end of this program, participants will be able to: Understand the benefits and limitations of thermal imaging Understand the different types of imagers available in the infrared spectrum Determine the important performance measurements of a thermal imager Understand what is needed to specify and apply thermal imagers 1. Describe the fundamental sensing mechanisms of thermal imagers. 2. Compare CMOS vs. CCD visible imager chip performance. 3. Determine when thermal cameras should be specified. 4. Compare thermal imagers from visible imagers under varying light and weather conditions. 4 Professional Education for the Security Industry

16 Components of a Thermal Imager Silicon ROIC Focal Plane Array (FPA) Cooled or Uncooled Detector Dewar/Cooler Assembly (DDCA) Optical Imaging Engine Thermal Imaging System Detector / Microbolometer -Vanadium Oxide -Amorphous Silicone -Barium Stronium Titinate (not a microbolometer) Final Packaging Enclosure, App Software, UI 16 Professional Education for the Security Industry

17 Important Specifications of Thermal Imagers: Type of detector - Vox vs. asi vs. BST for uncooled thermal imagers Sensitivity of detector- measured as Net delta T in mk - See 40mK to 100mK in the commercial sector Field of View options, not Focal Length - Focal length does not translate to the same FoV in thermal as it does with CCD or CMOS imagers Resolution - 160x120 vs. 320x240 vs. 640x480 Analog and IP versions are prevalent 17 Professional Education for the Security Industry

18 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 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. 18 Professional Education for the Security Industry
