摘要
未来的空间任务要求光学遥感器的口径越来越大,可展开光学系统是实现特大口径光学遥感器的主要技术途径之一,其主要特点是主镜分块、收拢发射、入轨展开,并且主镜超轻量化。文章分析了影响可展开光学系统主镜分块的因素,提出了主镜分块原则,在原则的指导下提出了约4m口径空间光学遥感器的主镜分块方案。
In the future, space missions such as high- resolution earth reconnaissance from the Geosychronous orbit, required the Space Optical Remote Sensor with large effective apertures. The deployable optical system was an effective way to realize the large aperture optics. The main characteristic of the space deployable optical system was the primary mirror, which was segmented, folded when launch and deployed in orbit. This paper analysed the factors which affect the segmentation of primary mirror and gave the principles of mirror segmentation. Finally, under the direction of the principle this paper gave the segmentation of the 4 - meter primary mirror.
