We investigate the design of an active support system for the thin primary mirror of a mid-sized telescope system used for optical satellite communication and space debris observation. To handle the complexity of this task, a general design methodology is proposed. The design for the axial and lateral support is separated into several subtasks to reduce the number of design variables in every design step. Due to the independence of mirror geometry and material, this methodology is also applicable to larger mirrors. Utilizing the proposed procedure, an active support for a 1-m meniscus mirror with 25 mm thickness and the requirement to achieve diffraction-limited optical performance is developed. The final system consists of 32 axial and 8 lateral actuators supporting the mirror with a maximal simulated RMS error of 8.8 nm and PV error of 48.0 nm when pointing to zenith. Simulations show that the obtained design ensures the required performance even under commonly occurring mirror deformations.

开发用于1-m弯月形薄镜的有源光学系统的设计方法

我们研究了用于光学卫星通信和空间碎片观察的中型望远镜系统的薄主镜主动支撑系统的设计。为了处理此任务的复杂性，提出了一种通用设计方法。轴向和横向支撑的设计分为几个子任务，以减少每个设计步骤中设计变量的数量。由于反射镜的几何形状和材料的独立性，该方法也适用于较大的反射镜。利用提出的程序，开发了一种厚度为25毫米，厚度为1毫米的弯月面镜的主动支撑件，并提出了实现衍射极限光学性能的要求。最终系统由32个轴向和8个横向致动器组成，它们支撑反射镜，其最大模拟RMS误差为8.8 nm，PV误差为48。指向天顶时为0 nm。仿真表明，即使在常见的镜面变形下，所获得的设计也可以确保所需的性能。
