大面阵红外焦平面探测器的漂移特性研究

The drifting characteristic research on large format infrared FPA detector

红外辐射特性测量是导弹预警和识别的主要手段,相关研究具有较大的军事应用价值。现在广泛地使用红外焦平面探测器进行目标的跟踪与辐射特性测量,介绍了红外测量系统的组成。在测量过程中发现红外探测器存在能量漂移现象,通过实验总结了红外探测器的漂移规律,同时分析了产生漂移现象的原因并提出了漂移补偿的方法。实验数据表明,漂移补偿能有效地减小测量误差,漂移补偿后的测温误差<1.5。

Infrared radiation characteristics measurement is the main method for the precaution and discrimination of missiles, relevant research is worthy in military application. Nowadays, infrared FPA detector is applied in the tracking and measurement of infrared target. The constitution of infrared measurement system is introduced. In the process of measurement, it is found that infrared detec- tor has the character of energy drift, the drift disciplinarians are summarized by experiment. Meanwhile, the cause of energy drift is analyzed and the drift compensation method is taken out. The experiment data indicates that drift compensation could minish the measurement error effectively. The temperature measurement error reaches less than 1.5 centigrade after compensation.
