Abstract

As a method to monitor the condition of complex super-characteristic materials, non-contact temperature measurement has been widely used in extreme environment measurement, but its temperature measurement results are greatly affected by the surface emissivity of complex materials. The characteristic trend of surface emissivity of complex materials is often uncertain and difficult to calculate directly due to many factors. In this paper, we propose a temperature measurement method for complex material surface multi-spectral data processing for simultaneous computational inversion of emissivity and temperature of complex materials. The inversion results show that the method can solve the problem of unknown surface emissivity of complex materials, and the temperature inversion error is less than 1%, which is expected to be applied to temperature monitoring in extreme environment for complex materials.

高温复杂材料表面的多光谱辐射温度数据处理算法

作为一种监测复杂超特性材料状况的方法，非接触式温度测量在极端环境测量中得到了广泛应用，但其温度测量结果受复杂材料表面发射率的影响很大。受多种因素影响，复杂材料表面发射率的特征趋势往往不确定，难以直接计算。本文提出了一种复杂材料表面多光谱数据处理的温度测量方法，用于同时计算反演复杂材料的发射率和温度。反演结果表明，该方法可以解决复杂材料表面发射率未知的问题，温度反演误差小于 1%，有望应用于极端环境下复杂材料的温度监测。
