摘要

摘要: 对基于中波红外焦平面探测器实现目标的表面温度测量进行了理论及实验研究。介绍了红外测温系统的组成和测量原理,建立了红外探测器测温模型。分析了标定过程中出现的红外探测器灰度值漂移现象,通过4种不同的实验方法总结了红外探测器灰度值漂移的规律,根据这些漂移规律提出了漂移补偿的方法。最后,以黑体为目标进行了测温实验。结果显示,漂移补偿前后的测温误差分别为1.965 ℃和0.335 ℃,表明测温精度得到了很大的改善。

Abstract: The surface temperature measurement of temperature target based on a medium wave infrared detector was researched theoretically and experimentally in this paper. The constitution and measurement principle of the system were introduced and a temperature measurement model for the infrared detector was established. The gray drift characteristics of the infrared detector in a calibration were analyzed, and the drift disciplinarians were summarized by four kinds of different experiments. Meanwhile, the drift compensation method was proposed based on the drift disciplinarians. Finally, a temperature measurement experiment was carried out, and the results show that the measurement error before and after drift compensations are 1.965 ℃ and 0.335 ℃, respectively, which indicates that the measurement precision has been improved in a great degree after the compensation.
