影响实用化实时测温系统测温精度的若干因素

Several affecting factors of temperature measurement accuracy for a practical temperature measuremen

摘要: 在介绍一种利用钽酸锂热释电探测器实现的实用化双波长光纤测温仪的基础上,着重讨论了反射辐射、探测器本身的辐射与环境温度、光路中选择性吸收气体的光谱吸收及除此之外的其他诸种因素对系统测温精度的影响,并提出了相应的抑制措施.

Abstract: The effect of reflection radiation, radiation of the detector itself,the surrounding temperature,the selective absorption gas in optical path, and other factors on temperature measurement accuracy for a practical temperature measurement system were discussed based on a practical dual-wavelength fiber-optic colorimeter using LiTaO_3 pyroelectric detector.
