| Abstract: | Two different phase reconstruct algorithms are deseribed in this paper. the principle and the practical formula of the reconstruct algorithms are mainly described. Using a HS plate with hole array instead of HS wavefront sensor, the phase of Starlight II 1012W high power laser is measured. And the results of two reconstructed phases are analyzed. The P-V (peak-valley) and RMS (root-mean-square) values are also compared. |
