英文摘要	Aiming at the demand of high-precision space-based optical quantitative remote sensing, a self-calibrated spectral radiance standard source which employs Digital Micromirror Device (DMD) was developed. The light source has two working modes. In narrow-band mode, it is calibrated by CAS spectroradiometer and Gershun radiometer. In broad-band mode, it is used for calibration of the spectral radiance responsivity of ground-based or space-based remote sensing instruments. An spectral radiance standard source comprised by spectral irradiance standard lamp and Spectralon standard plaques was adopted to calibrate CAS spectroradiometer, which was used to measure the spectral radiance of the self-calibrated source. Meanwhile a Gershun radiometer calibrated by a standard detector was used to measure the self-calibrated source, thus the spectral radiance of the source was achieved by iteration. The measurement results of the two calibration methods are coincident within the measurement uncertainty range. The uncertainty analysis shows that the uncertainties of the spectral radiance based on standard source calibration and based on standard detector calibration are 1.41%~2.09% and 1.28%~1.61% respectively. The results of the experiments and the uncertainty analysis indicate that the self-calibrated spectral radiance standard source can meet the requirement of the space-based optical quantitative remote sensing. 2017, Science Press.
