The two wavefront retrieved by reconstructor and the incident wavefront. (a) By directly differential (PV: 23.84λ, RMS: 4.36λ, x scale or y scale: 4 μm/div). (b) By CPCS (PV: 23.72λ, RMS: 4.35λ, x scale or y scale: 4 μm/div). (c) The incident wavefront (PV: 25.62λ, RMS: 4.49λ, x scale or y scale: 4 μm/div).
