Shape based zonal wave-front reconstruction for arbitrary shape pupils

Zonal method is widely used to reconstruct the wave-front. Up to now, the iterative algorithms have been used to reconstruct the arbitrary shape wave-front with high reconstruction accuracy. However, it has the shortcomings of long time consumption. To reduce the time delay, a shaped based method is proposed by adding the shape information into the geometry matrix. The simulated and experimental results indicate that the reconstruction accuracy of proposed method is similar to that of the iterative LS-based method, but the computation time of our method is 3 times less than that of the iteration method. Consequently, the high accuracy and low time consumption are simultaneously achieved with the proposed method.
