The design method of initial structure discretization based on Chebyshev points was used to design and solve the freeform surface, and the feasibility of the design method was verified by optical simulation. The designed freeform surface is machined and tested, and the test results show that the surface roughness root mean square (RMS) of the freeform reflector is 0.61\u2005\u03bcm, which indicates that the continuity of the machined surface is good. The optical characteristics of the calibration light source system are measured, the results show that the irradiance uniformity and radiance uniformity are better than 98% in the effective illumination area of 100\u2005mm\u2009\u00d7\u2009100 mm on the target plane. The constructed freeform reflector calibration light source system can meet the requirements of large area, high uniformity and light weight for onboard calibration of the payload of the radiometric benchmark, improving the measurement accuracy of spectral radiance on the reflected solar band.<\/jats:p>","DOI":"10.1364\/oe.481105","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T09:00:10Z","timestamp":1674637210000},"page":"8049","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Freeform reflector light source used for space traceable spectral radiance calibration on the solar reflected band"],"prefix":"10.1364","volume":"31","author":[{"given":"Ye","family":"Jiang","sequence":"first","affiliation":[{"name":"Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiewen","family":"Tian","sequence":"additional","affiliation":[{"name":"Northern Institute of Electronic Equipment of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Fang","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denghui","family":"Hu","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of Chinese Academy of Science"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Ye","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,2,17]]},"reference":[{"key":"oe-31-5-8049-R1","doi-asserted-by":"publisher","first-page":"237","DOI":"10.1007\/s11707-010-0002-z","volume":"4","author":"Xiong","year":"2010","journal-title":"Front.
