Abstract

In many optical systems, to meet the need of dynamic controlling the large aperture thin mirror surface shape when different loads are applied on the mirror, based on the thin plate bending theory, the quantitative relationship between the loads and the deformation of the mirror is studied in detail when axisymmetric load or eccentric load is applied on the mirror respectively. The shape of the mirror surface is analyzed by numerical calculation respectively. Results show that the mirror deformation is axisymmetric and the maximum deformation occurs at the circle center when axisymmetric loads are applied on the mirror. Meanwhile, the PV value and RMS value of the mirror deformation increase with the multiple relationship of load increase. When eccentric loads are applied on the mirror, the mirror deformation is not axisymmetric. And the intensity and position coordinates of the load will have a great influence on the PV value and RMS value of the mirror deformation.
