【摘要】 随着光学成像系统的大口径化和高分辨率化发展的趋势,拼接孔径技术成为了突破传统光学系统高分辨率极限的关键技术之一。针对拼接孔径光学系统的成像特点和实现方式,进行光学系统的设计和同心度检测方法的研究。包括:系统的总体设计;各光学参数和结构的确定;孔径拼接方案的选择;具体的光学设计和同心度检测方法的探讨。最终设计一个全口径1米,焦距8000mm,全视场角为0.08°,主反射镜由1块母镜加9块子镜拼接的附加透镜组的卡塞格林式光学系统,实现消色差,光学传递函数接近接近衍射极限的优良成像质量。此外,提出利用直角屋脊棱镜作为检测棱镜,进行同心度的自准直检测。更多还原

【Abstract】 With the rapid development of large aperture optical systems and high resolution of imaging optical systems, aperture-stitching technique has been one of the most important techniques that can efficiently and feasibly break the resolution limit of traditional optical system.In view of the imaging character and implementation of aperture-stitching optical system, the design of the optical system and the concentricity measurement is concerned in this paper. It is composed of the total design of the system, the confirmation of optical and structure parameter, the selection of the plan of the aperture-stitching and the optical design and measurement plan.The Cassegrain optical system, which has 1m aperture, 800mm focal length and the field-view angle of 0.08°is designed. The ’1+9’ aperture-stiching model is applied in this paper. The color aberration is eliminated and the optical transfer function is really very near to the limit of diffraction. In addition, the right-angle roof prism is applied as test prism to realize the auto-test of the concentricity.更多还原
