a Iterative optimization of a random combination of Zernike mode amplitudes with metric S4 during laminar flow of seeding particles in a water basin. The seeding particles appear blurred and deteriorated in shape for the disturbed and sharp for the corrected case. b Applied (red) and iteratively determined (green) Zernike mode amplitudes of the deformable mirror
