| 中文摘要: | Based on a 979-actuator adaptive optics system, this paper analyzes the different performance of iterative wavefront reconstruction algorithms. Under the condition of dynamic wavefront errors, the iteration number, storage space and the number of multiplication of steepest descent method, conjugate gradient method and G-S iterative method are studied. The steepest descent method and conjugate gradient method need smaller storage space. Both the G-S iterative method and the conjugate gradient method converge faster than steepest descent method, while the latter takes the least number of multiplication. Finally, the optimal iterative algorithm is selected considering storage space, iteration numbers and the number of multiplication. © 2014 SPIE. |
