P3 - Modeling Signal-Determining Radiation Components of Microbolometer-Based Infrared Measurement Systems

TL;DRAbstract

This paper studies influences of changing external temperature conditions on radiation measurement using microbolometer-based infrared focal plane arrays (FPA). The effect of thermal drift on the radiation measurement using TEC-less infrared cameras is compared to the effect on measurements with TEC. Sensor specific parameters are analyzed and their correlations due to variations in temperature are described. Using a simplified radiation measurement set-up the influence of a defined temperature gradient on the measured radiation signal is analyzed and compared with the calculated radiation responds.
