摘　　要：为了解决微机械薄膜变形镜的由于整体薄膜宽交连值、单向形变所引起的Zernike模式像差校正能力较低的问题,采用了一种基于主成份分析的波前模式分析方法,方法利用对微机械薄膜变形镜驱动电极影响函数的相关分析,并对新向量组进行了降维处理,得到的模式复原波前基向量有助于减少测量噪声和计算误差的影响。方法对于基于微机械薄膜变形镜的模式控制电压的求解有着重要意义。Wavefront modal analysis based on principal component analysis was put award in order to solve the low ability to correct the wavefront, which is due to the great intercourse and one-direction transforming of the whole membrane of microma chined membrane deformable mirror（MMDM）. By analyzing the correlation of the influence function of control electrode of MMDM and reducing the dimensional number of new influence function vectors, the basic vector of modal reconstruction can reduce the influence of the calibrating noise and calculation error. It is significant to solve the control voltages of modal reconstruction based on the MMDM.
