Abstract

Additive manufacturing (AM)-layer-by-layer printing-completely changes the conventional manufacturing method. The design freedom for mirrors is increased without the limits of the manufacturing process. Advanced lightweight mirrors (ALM), new-type mirrors designed using the generative method and lattice technologies, have emerged as the times require. Contrasting with conventional lightweight mirrors (CLM), the performances of ALM are drastically improved. This paper took the Voronoi mirrors as an ALM case study and introduced a design flow. In addition, a conventional honeycomb mirror was designed using the analytical method as the control. The optomechanical performances of the two were further compared through finite element analysis (FEA). Finally, ALM's optomechanical performances outperformed CLM's, including the area density, structural stiffness, surface stability, and quilting deflection.

摘要

增材制造（AM）——逐层打印——彻底改变了传统制造方法。镜子的设计自由度得以提高，不再受制造工艺的限制。先进轻质镜（ALM），即采用生成式方法和点阵技术设计的新型镜子，应运而生。与传统轻质镜（CLM）相比，ALM的性能得到了大幅提升。本文以Voronoi镜为例对ALM进行了研究，并介绍了一种设计流程。此外，还采用解析法设计了一种传统蜂窝镜作为对照。通过有限元分析（FEA）进一步比较了两者的光机性能。最后，ALM的光机性能优于CLM，包括面密度、结构刚度、表面稳定性和绗缝变形。
