%X Through the complete analysis of a radiometric calibration process, the uncertainty trasfer relationship between absolute calibration and relative calibration is revealed. In the analysis, the multi-point radiometric calibration method is used for the relative calibration and the standard lamp---diffusion board---integrating sphere routine is used for the absolute calibration. By taking this radiometric calibration chain as a model, the uncertainty equations in the radiometric calibration chain are given and the uncertainty factors due to the relative calibration in these equations are analyzed. Finally, the uncertainty values which can be achieved with the current equipment are calculated. These values are helpful theoretically to the determination of the precision requirement for lab radiometric calibration.
