Study on temperature drift compensation of infrared thermal imaging system
红外热成像系统温度漂移补偿算法研究

Influenced by environmental temperature, infrared focal plane arrays (IRFPA) response output has obvious temperature drift after working for a long time, which causes larger temperature measurement error of infrared thermal imaging system(ITIS). Therefore, a temperature drift compensation algorithm of ITIS is presented. The algorithm establishes a temperature compensable model for IRFPA response output drift with the environmental temperature, which can correct the drift value of every detector response output. With this compensation algorithm, some infrared object temperature display experiments in ITIS have been done.The experimental results show that the algorithm can effectively reduce temperature drift caused by the environmental temperature, and temperature measuring accuracy of ITIS can be greatly improved.
