Paper Abstract

We present our design procedure for a 1-m lightweight mirror in a space optical system. The glass mirror has three monolithic bosses at the rim and is assembled with metallic bipod flexures. Their dimensional parameters cannot be optimized independently with each other in a classical design process, where optical performance is greatly affected by the flexure mount configuration. With our method, the design problem is separated into two independent problems; mirror design and flexure design. Resources required to achieve design goals are reduced by almost one order of magnitude in time. Also the mirror and flexure mount designs can be parallel-processed without interfering each other. In this paper, we present the mirror design process and its results optimized with multi-objective genetic algorithm (GA).
