摘    要:根据热辐射理论和红外成像仪的测温原理,系统分析了各种因素对红外热成像仪测温的影响,并根据被测物体表面的发射率、吸收率、大气透射率、环境温度和大气温度本身及其对误差测温误差影响的理论计算公式,分析了各种误差对测温误差的影响程度,并讨论了减小误差的对策。

关 键 词:红外热成像仪  温度测量  误差分析  热测量

Abstract:Based on the theories of thermal radiation and of the infrared thermography, this thesis analyzes almost all kinds of factors including the emissivity of the surface of the object to be measured and atmo sphere systematically. The temperature of the environment and the working waveband of the thermography, etc., Will effect on the error in infrared measurement. The countermeasures to reduce the error are also discussed.
Keywords:infrared thermography  thermal measurement  error analysis
