Uncertainty Estimation of Size-of-source Effect Measurement for 650 Nm Radiation Thermometers
نویسنده
چکیده
− This paper describes the uncertainty estimation of the size-of-source effect (SSE) measurement for the standard radiation thermometers in the indirect method using an integrating sphere with a black spot as the source. We checked the agreement between two processes of changing the black spot size and changing the aperture size. The SSE contributions of each uncertainty factors were analyzed.

Measurements of the Size of Source for Pyrometers Directly Indicating in Temperature
− The calibration of radiation thermometers requires knowledge of the target size effect on the thermometer output, namely the size of source effect (SSE). The measurement of an instrument SSE allows to calculate a correction, or an estimation for this source of uncertainty. For a correct determination of SSE it is necessary to use large aperture radiation sources of uniform spectral radiance. ...
