Highly Accurate Calibration of Optical Radiation Based on Cryogenic Radiometer at Visible and Near Infrared Spectrum (488~944 nm)
Report the research on highly calibraton 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%.
