基于亚历山大效应的光谱高温仪校准方法研究

Research on Spectropyrometer and Correction Method Based on Alexandrite Effect

介绍了亚历山大效应,分析了基于该效应的光谱高温仪的温度测量原理,即"温度-光谱-色彩角"的关系,建立了光谱高温仪光谱测量模型,提出了3000℃以下温度范围的光谱高温仪的校正方法,以及3000℃以上的光谱高温仪校正路径。

This paper analyzes the measurement principle of spectropyrometers based on Alexandrite Effect, i.e. the ＂temperature -spec- trum - hue angle＂ relationship, and establishes a spectrum measurement model of spectropyrometer. A correction method is put forward for the situations with the temperature under 3000℃ and a correction notion is proposed for the situations with the temperature over 3000℃.
