摘要 报道了可见-近红外波段(488~944 nm)基于低温辐射计的光谱辐射功率定标和标准传递实验和研究,并对测量结果的各个不确定因素进行了测量和分析.首先低温辐射计采用电替代方法测量单个波长激光绝对光功率,测量不确定度低于0.016%.然后利用低温辐射计定标作为标准传递探测器的硅陷阱探测器,从而建立可见-近红外波段陷阱探测器的绝对光谱响应率标准,其不确定度小于0.028%.结果证明了在此波段以探测器为基础建立和传递高精度光辐射标准的合理性和可行性. The research on highly calibration and standard transfer is based on cryogenic with analyzing the component uncertainties which contribute to total uncertainty associated with the measurement results. Firstly, the laser power was measured by cryogenic radiometer in visible and near infrared spectral regions (488-944 nm), uncertainty of power measurement is less than 0.016%. Secondly, Si transfer standard detectors were directly calibrated against the cryogenic radiometer using laser source, therefore the absolute spectral responsivity scale is established at this spectral regions (488-944 nm) at uncertainty less than 0.028%.
