摘要	The calibration method used for spectral radiance of the vacuum ultraviolet band (115-200 nm) was studied to calibrate the radiation parameter of VUV radiometer at 115 nm. Two calibration methods were designed to solve the following problems: low uniformity of calibration source, long value transfer chain, and insufficient lower limit of calibration band. In the method based on standard diffuse reflectors, the VUV bidirectional reflectance distribution function/bidirectional transmittance distribution function (BRDF/BTDF) measurement standard component was developed to measure the lowest wave band at 115 nm. In the method based on standard radiometer, the standard design method of spectral radiance transfer was proposed, and the experimental verification was completed with a field angle of 2. A new preparation method of a standard vacuum ultraviolet diffuse transmitter was proposed and its measurement was carried out, revealing good Lambert characteristics in the range of 10. The calibration devices were developed and the value transfer chain and measurement uncertainty were analyzed, revealing a reduced BRDF measurement uncertainty component with better measurement uncertainty. A calibration test of payload on FY satellite was carried out using the calibration device. The uncertainty of spectral radiance measurement in the range of 115-200 nm is 12%(k=2), and the payload runs well in orbit. This research on the calibration method and VUV spectroradiometer is of great significance to the research and application of VUV space exploration technology. 2022, Science Press.
