摘要
在多光谱辐射温度计的数据处理中常假设发射率的对数与波长成线性关系,本文提出一种自动判别发射率和波长数学模型的新方法,着重分析了应用此方法时各种测量误差对真温及发射率的影响.计算机仿真结果与理想假设值符合得很好,是一种较好的获知真温及发射率的方法.
In general, the dependence of the logarithm of the emissivity upon wavelength is usually used in the data processing measured by multiwavelength pyrometer. In this paper, a new method for automatically searching the mathematical model between emissivity and wavelength was proposed. The effects of measurement errors on the temperature and emissivity were emphatically analysed when the abovementioned method was used. The results of computer simulation match extremely well with the assumed data. The theory developed here has been shown to be an effective method to calculate both temperature and emissivity.
