摘要
面向天基空间探测应用,设计了较大视场(FOV)的超分辨望远成像光学系统。对于含低旁瓣因子五环带纯相位光瞳调制器的系统,分别研究了各类像差及调制器误差对其超分辨参数的影响。指出在超分辨望远成像系统中,非对称性像差需严格抑制,而对称性像差影响较小,且可互相补偿。根据此结论,优化设计了全视场内像质均一、残留一定量球差的宽FOV大口径望远光学基底系统,加入调制器后,其在0.28°视场内具有圆整且十分相似的PSF,超分辨倍率不小于1.25,旁瓣因子小于0.1。基于超分辨望远系统特点,建立了合理的像差容限模型,有效地控制了加工成本与难度。
Abstract
A super-resolution telescope imaging optical system with a relatively wide field of view (FOV) is designed for space-based spatial exploration applications. The effects of various aberrations and modulator error on the super-resolution parameters of a five-ring pure phase pupil modulator with low side lobe factor are studied herein. The asymmetric aberrations in the super-resolution telescope imaging system are required to be strictly suppressed; however, the influence of these symmetrical aberrations is small, and different kinds of symmetrical aberrations can compensate each other. Therefore, a wide FOV and large aperture telescope optical baseline system having uniform image quality and certain amount of spherical aberration is optimally designed. When the modulator is added, it has a round and identical PSF in 0.28° FOV, and the super-resolution ratio is not less than 1.25. Furthermore, the side lobe factor is less than 0.1. According to the characteristics of super-resolution telescopic system, a reasonable aberration tolerance model is established, which effectively controls the cost and difficulty of machining and assembly.
