英文摘要	In the field of space remote sensing technology, designing a long focal length, high resolution, compact optical imaging system is one of the current hotspots in the research of micro/nano satellites. Based on the general working lens structure and actual imaging requirements of micro/nano satellites, this paper uses paraxial imaging methods to analyze and calculate the various indicators of the lens. A high-resolution coaxial refractive optical system for space remote sensing satellites is designed. The system has the characteristics of long focal length, high resolution, and compact structure. Its working band is 380nm-780nm, focal length f is 1200mm, F/ # Is 6, the field of view angle can reach 2ω=1.4°. When the satellite orbit height is 420km and the sensor pixel size is 4.25μm, the geometries resolution GSD can reach 1.5m. Through multiple optimizations of the parameters, the final designed optical system has a full field of view MTF value greater than 0.28 at a spatial frequency of 188lp/mm, and the imaging effect is excellent, close to the diffraction limit. © 2020 COPYRIGHT SPIE.
