Fig. 3.

Reconstruction from uncorrected FPM and EPRY-FPM algorithms using FPM blood smear data set. The initial guess of the pupil function is a circular shape low pass filter with no phase, and the reconstructed region is located 35% from the center of the FOV. (a1-a2) Reconstructed sample intensity and phase using uncorrected FPM algorithm. (b1-b2) Reconstructed sample intensity and phase using EPRY-FPM algorithm. (c1-c2) Reconstructed pupil function modulus and phase using EPRY-FPM algorithm. (d) Zernike decomposition of pupil function phase, the amplitude of the lowest 30 modes (representing the 30 lowest order aberrations) are shown.
