Matlab code implements Fourier ptychography reconstruction algorithm from a set of images captured under different illumination angles (e.g. in an LED array microscope), using either sequential or multiplexed coded illumination. The algorithm simultaneously estimates the complex object function (amplitude + phase) withhigh resolution (defined by objective NA+illumination NA) and the pupil function (aberrations). It implements a sequential quasi-Newton’s method with Tikhonov (L2) regularization.
