In this paper, the time-delayed integration (TDI) of the digital domain is applied to solve the issue of insufficient light energy brought by high spatial resolution, and a hyperspectral camera with linear variable filters suitable for digital domain TDI technology is further designed. The camera has a wavelength range of 450\u2013950 nm, with an average spectral resolution of 10.2 nm. The paper also analyzed the effects of digital domain TDI on the signal\u2013noise ratio (SNR) and the spectral resolution. During its working in orbits, we have obtained high-SNR images with a swath width of 150 km, and a ground sample distance (GSD) of 10 m @ 500 km. The design of the hyperspectral camera has an improved spatial resolution while reducing the cost.<\/jats:p>","DOI":"10.3390\/s21072276","type":"journal-article","created":{"date-parts":[[2021,3,24]],"date-time":"2021-03-24T21:36:51Z","timestamp":1616621811000},"page":"2276","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The Instrument Design of Lightweight and Large Field of View High-Resolution Hyperspectral Camera"],"prefix":"10.3390","volume":"21","author":[{"given":"Xinghao","family":"Fan","sequence":"first","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Key Laboratory of Space-Based Dynamic &amp; Rapid Optical Imaging Technology, Chinese Academy of Sciences, Changchun 130033, China"}]},{"given":"Chunyu","family":"Liu","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"Key Laboratory of Space-Based Dynamic &amp; Rapid Optical Imaging Technology, Chinese Academy of Sciences, Changchun 130033, China"}]},{"given":"Shuai","family":"Liu","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"Key Laboratory of Space-Based Dynamic &amp; Rapid Optical Imaging Technology, Chinese Academy of Sciences, Changchun 130033, China"}]},{"given":"Yunqiang","family":"Xie","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Key Laboratory of Space-Based Dynamic &amp; Rapid Optical Imaging Technology, Chinese Academy of Sciences, Changchun 130033, China"}]},{"given":"Liangliang","family":"Zheng","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"Key Laboratory of Space-Based Dynamic &amp; Rapid Optical Imaging Technology, Chinese Academy of Sciences, Changchun 130033, China"}]},{"given":"Tiancong","family":"Wang","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"Key Laboratory of Space-Based Dynamic &amp; Rapid Optical Imaging Technology, Chinese Academy of Sciences, Changchun 130033, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2090-6032","authenticated-orcid":false,"given":"Qinping","family":"Feng","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Key Laboratory of Space-Based Dynamic &amp; Rapid Optical Imaging Technology, Chinese Academy of Sciences, Changchun 130033, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1016\/j.optcom.2019.03.064","article-title":"Design of a compact spectrometer with large field of view based on freeform surface","volume":"444","author":"Feng","year":"2019","journal-title":"Opt.
