热辐射测量技术中,红外探测器的非线性效应导致对目标红外辐射测量时存在一定误差。 依据黑体辐射定律,理论计算得出黑体在不同温度、一定波长带宽下的热辐射量曲线,实验测得同样参数 下红外探测器检测到的热辐射量。利用理论曲线对探测器的检测曲线进行修正,校正探测器非线性效应, 提高热辐射测温的测量精度。

In the thermal radiation measurement technology, the nonlinear effect of infrared detector leads to some error in target infrared radiation measurement. Based on blackbody radiation law, the thermal radiation curve of blackbody at different temperatures and certain wavelength and bandwidth is calculated theoretically. The thermal radiation measured by infrared detector is obtained experimentally with the same parameters. The detection curve of detector is modified by the theoretical curve. The nonlinear effect of detector is corrected, and the measurement accuracy of thermal radiation temperature measurement is improved.
