Fig. 6: Wavefront sensor-less method performance.

In (a) the calibration test original HSPM image is shown. The sample is slightly defocused to add an additional aberration. In (b) the initial reconstruction after applying the method is shown. In (c) the merit function evolution for Zernike’s coefficients \({Zn}\) from 3 to 5 is shown. Additionally, in the left-bottom corner of (c) the normalized phase map codified in the lens is shown.
