| 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. |
