DigiTHERM is IGI's airborne thermal camera system for professional digital aerial thermography. With a thermal resolution of 0.05K, the standard temperature range is -40°C to 120°C. The uncooled microbolometer FPA-detector with 640x480 pixels delivers brilliant thermal images in high quality. Using a graphical user inferface with real time preview, no additional video system is required. Both featuring rugged metal housings and being part of IGI's Modular Sensor Systems, DigiTHERM and DigiCAM are extremely robust and can be exchanged conveniently and inexpensively during airborne missions. Combined with IGIplan, CCNS4 and AEROcontrol GPS/IMU system, DigiTHERM forms a complete solution for an extremely rapid and automated workflow for the generation of directly georeferenced thermal images.


Modular System Concept

DigiTHERM is one part of IGI's Modular Sensor Systems. Its components consist of a thermal camera, a DigiControl SMU with hot swap storage unit for up to 36 hours of flying time and an 8 inch TFT touch-screen. Using the same components as DigiCAM, the changeover between the two systems is realised within minutes.
