Simulation Study of Wavefront Reconstruction Algorithms in DCAO System

In this paper, we present a analytical study of the wavefront reconstruction algorithm for DCAO system. This algorithm is based on Zernike polynomials. We simulate the wavefront reconstruction using Zernike expansion in classical AO system and in DCAO system, and compare the reconstruction performance of the two systems. Through the simulation, we can see, the wavefront we reconstructed in DCAO system is more similar to the initial wavefront. With the analysis of the simulation results, we come to the conclusion that this algorithm has good effect in wavefront reconstruction in DCAO system.
