In this paper, the reliability of infrared thermal imagers is studied. Typical failure modes and accelerating factors of thermal imagers are summarized and a classical reliability model is established. Based on the theoretical analysis of the limiting factors, the design technologies of high reliability thermal imagers are presented, which are verified by several reliability simulation tests. Furthermore, the development of reliability of the domestic and foreign thermal imagers is introduced.
