One key step for full field correction is to match the main laser amplitude distribution with beacon amplitude distribution on deformable mirror 2 in two-deformable-mirror adaptive optics. Amplitude and phase corrections for turbulence are studied based on Y-G wavefront retrieval algorithms. The results show that full field corrections can improve Strehl ratio by a factor of 1.27 to 2.50 compared with phase-only correction. For a distance of 10m between deformable mirror1 and deformable mirror 2, the factor is from 1.13 to 1.50.
