Solar stray light is a fatal problem for optical satellite works in the polar orbit, even for nighttime scene imaging, resulting in image saturation and light signal detection failure. To solve this problem, an analysis of the range of solar incident angles was conducted firstly. Based on the result, a special-shaped baffle was designed to avoid direct sunlight incidence. Moreover, the capability of stray light elimination of the lens was enhanced by an order of magnitude via optimizing the internal structure. An evaluation of secondary scattering stray lights into the camera from surrounding parts was performed based on a real satellite model. The results showed that the stray light elimination reaches a 10\u221210 order, meeting design requirements. Utilizing on-orbit images, the ability of satellites in illuminated areas to obtain artificial lights in dawn-dusk area was verified, proving the effectiveness of the stray light elimination design.<\/jats:p>","DOI":"10.3390\/s19051130","type":"journal-article","created":{"date-parts":[[2019,3,7]],"date-time":"2019-03-07T10:52:22Z","timestamp":1551955942000},"page":"1130","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Analysis and Reduction of Solar Stray Light in the Nighttime Imaging Camera of Luojia-1 Satellite"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8819-4687","authenticated-orcid":false,"given":"Xing","family":"Zhong","sequence":"first","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130102, China"},{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiqiang","family":"Su","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130102, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3987-5336","authenticated-orcid":false,"given":"Guo","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Remote Sensing and Information Engineering, Wuhan University, Wuhan 430079, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhigang","family":"Chen","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130102, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao","family":"Meng","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130102, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deren","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, Wuhan University, Wuhan 430079, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Liu","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130102, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,6]]},"reference":[{"key":"ref_1","first-page":"591","article-title":"An overview on data mining of nighttime light remote sensing","volume":"44","author":"Deren","year":"2015","journal-title":"Acta Geod.
