提出了一种改进的并行广义投影算法，允许按加权范数使用投影。证明了改进的加权并行广义投影算法的收敛性质。将加权并行广义投影算法应用于两个有限分辨率可变形反射镜的控制，以补偿在湍流介质中传播引起的幅度和相位起伏。数值结果表明，双变形镜系统比单变形镜系统具有更好的性能。
A modification of the parallel generalized projection algorithm is presented that allows for the use of projections in a weighted norm. Convergence properties of the modified algorithm, denoted the weighted parallel generalized projection algorithm, are developed. The weighted parallel generalized projection algorithm is applied to the control of two finite-resolution deformable mirrors to compensate for both the amplitude and the phase fluctuations that result from propagation through a turbulent medium. Numerical results are shown that indicate that a two-deformable-mirror system can provide improved performance over that of a single-deformable-mirror system.
