将基于标定模式的双色测温拓展为基于非标定模式的三色比值辐射测温,以此为出发点,考虑测量不确定度的影响,开展辐射测温的反演算法、光谱组合等优化分析。研究了非标定模式的比值辐射测温与标定模式的双色测温的优劣,对于非标定模式的比值辐射测温,当测量不确定度较大时,通过比较分析,提出了推荐采用的反演算法。同时,针对于具有应用优势的非标定比值辐射测温模式,讨论了光谱组合优化选择的问题,采用遍历模拟的方式,得到了特定条件下的优化光谱组合结果。给辐射测温方法与技术的改进与应用提供重要的指导。

英文摘要：

Three-color pyrometry with the non-calibration mode was used as an extension of two-color pyrometry.Based on the inherent measurement uncertainties,the analyses of pyrometry optimization were carried out.The optimization purpose was to investigate the effects of inverse algorithms and wavelengths combinations on temperature measurements.Through numerical simulations based on the measurement uncertainties,different iterative algorithms for three-color method and traditional two-color method were compared to determine the optimum iterative algorithm.The choice of wavelengths combination is another important optimization issue.Due to the coupling characteristics of data processing of three wavelength channels,the effects of spectrum wavelengths to measurements greatly differed from the disposals of single-color method and two-color method.Through numerical analyses,the optimization combinations of three wavelengths under the specified measurement conditions were also obtained.The above discussions are necessary for the actual measurement applications of pyrometry.
