摘要
介绍了基于黑体标定的目标表面温度测量系统的系统组成及测量原理,利用黑体对红外探测器标定得到表面温度的测量曲线。分析了红外探测器的漂移特性,拟合漂移曲线并对探测器的能量漂移进行补偿。对一个温度可控的面辐射源进行测温实验,比较漂移补偿前后的测温数据,补偿后的测温精度得到了明显的提高。
The principle and configuration of surface temperature measurement system based on blackbody demarcation is introduced,and the blackbody is used to demarcate the IRFPA in order to gain the surface temperature＇s measurement curve. The drift characteristic of IRFPA is analyzed, and the drift curve is fit to compensate the energy drift. Measurement experiment is carried through on a radiation target which temperature is controllable, the measurement data is compared between the fore-and-aft compensation. The precision of temperature measurement after compensation is improved obviously.
