摘　　要：采用形状函数法描述变形镜校正时的曲面,从适配误差、Streh l比两方面比较了四种不同单元排列方式的微变形镜。结果表明方形与砖形排列的微变形镜设计简单,但波前校正性能较差;圆形及蜂窝形微变形镜具有较高的波前校正性能,但设计加工复杂。Shape functions were used to describe the surfaces of the micro deformable mirrors in working state, and then four kinds of micro deformable mirrors with different arrays were designed for the simulation of the aberrated wavefronts correction. And their performances were compared from fitting error and Strehl ratio. The results show that the square array and the brick array are easier to design, but its performance is not good. The circular array performs best ,but is more difficult to design.
