Abstract
This paper presents the design and simulation results of a MEMS-actuated deformable mirror (DM) consisting of a 20 × 20 Lorentz-force actuator array bonded to a flexible mirror. The DM is the critical component of an Adaptive Optics (AO) system targeted for ground-based telescope applications to actively compensate for optical aberrations due to atmospheric turbulence. In addition, there are several other applications for such AO systems, including microscopy, medical imaging, and optical communication. In order to meet the needs of various applications, Finite Element Method simulation of actuator performance is carried out using COMSOL Multiphysics software.
