Low temperature measurement capability analysis and test verifications of infrared thermal imager in the thermal environment test

  • 摘要: 文章分析了红外热像仪在航天器热试验中对低温目标的测温能力不足问题,采用红外干扰消减以及分段辐射定标/分段线性函数拟合的方式,初步解决了红外热像仪在真空低温环境下对低温目标的测量受限的问题。文章的研究结果有助于改进红外热像仪在真空低温环境下的非接触温度测量工作。

     

    Abstract: In this paper, it is shown that the infrared thermal imager is not adequate in measuring the temperature of the cold object in the spacecraft thermal test environment. The methods are proposed to eliminate the infrared disturbance and to scale the section with the section linear fitting, in order to solve the problem. The research results can be used to improve the non-contact temperature measurement for the infrared thermal imager in the vacuum cold environment.
