Combination of ten solutions: (a) the first eigen-solution obtained by computing an eigenvalue decomposition (76% weight), (b) average of the solutions (c) line cut (indicated in orange in (b)), with the first eigen-solution in red, the average solution in black, the best individual solution in blue, and in gray the first eigen-solution when combining only the 4 best solutions (weighting 99% of the 4 solutions). (d) 2nd and (e) 3rd eigen-solutions in the ten mode decomposition. (f) phase retrieval transfer function computed for the different types of solutions. The solution obtained through eigen-decomposition of the 10 solutions yields a higher correlation at high frequencies, and presents lower background noise levels compared to the average solution. Combining only the 4 best solutions yields a higher PRTF.
