用于大调制量音圈变形镜的驱动器优化设计
Optimization of actuator for voice coil deformation mirror with large phase stroke
摘要
Abstract
The voice coil deformation mirror,due to its large modulation and lack of hysteresis,is widely used as an adaptive secondary mirror in astronomical telescopes.This paper proposes an optimization method for the voice coil driver used in a 37-element large modulation voice coil deformation mirror,followed by simulation and validation.A dynamic magnetic structure is utilized to derive the theoretical formula for the electromagnetic force of the driver and the relationship between the electromagnetic force and mirror surface strain is briefly discussed.Detailed optimization of the structure is conducted using finite element software.Ultimately,simulation analysis and aberration correction validation of the 37-element voice coil deformation mirror are performed based on the optimization results.The designed voice coil driver has an efficiency of 0.362 N/W1/2,a response speed of 0.3 ms,linearity of 1,and allows for a maximum deformation mirror stroke of 50 μm.Moreover,the designed driver excels in simplicity,miniaturization,low cost,high response speed,linear response,and high efficiency,indicating promising applications in atmospheric turbulence aberration correction,laser weapons,laser communication,and fundus imaging.关键词
