在比色测温中,高温背景辐射对准确测量目标温度有很大的干扰,利用蒙特卡洛法通过概率 分布模拟背景辐射的发射位置、辐射方向和反射或吸收特性,统计被测量目标反射并被探测 器检测到的辐射能束,与理论辐射差值相比较,检验其准确性。在此基础上,提出一种在复杂 环境下消除高温背景辐射影响、提高测温精度的方法。

In colorimetric temperature measurement, high temperature background radiation interferes with the accurate measurement of target temperature. Monte Carlo method is used to simulate the emission position, radiation direction, reflection and absorption characteristics of background radiation by probability distribution. The radiant energy beam reflected by the target was detected by the detector and compared with the theoretical radiation difference to verify its accuracy. On this basis, a method that can eliminate the influence of high-temperature background radiation in a complex environment and improve the accuracy of temperature measurement is proposed.
