Integrated Optomechanical Analysis of the Impact of an Ø 800 mm Primary Mirror on the Imaging Quality of an Optical System

With the rapid advancements that are occurring in space technology, there is an increasing demand for improvements in the image quality of high-resolution space optical telescopes. The optical performance of the primary mirror plays a crucial role in determining the overall image quality of these optical systems. In this study, we analyze the rigid-body displacement and mirror deformation of an optical mirror in terms of the entire satellite hierarchy, utilizing integrated optomechanical analysis methods to assess the modulation transfer function (MTF) of the optical system. Additionally, we simulate MTF degradation under gravitational effects. Further, we conduct an experimental optical detection test on the main mirror assembly to validate our simulation analysis. This study provides valuable insights into structuring whole-satellite layouts and designing mirror support structures.
