Ptychography is an enabling microscopy technique for both fundamental and applied
sciences. In the past decade, it has become an indispensable imaging tool in most X-ray …

Noise, one of the severe challenges in phase retrieval, may bring the algorithms to fall into
local minima or even disrupt the convergence, thereby adversely affecting the imaging …

The resolution of lensless on-chip microscopy is mainly limited by the pixel size of the image
sensor. Many super-resolution techniques have emerged to solve the problem of insufficient …

A linear model by writing the recorded diffractive intensities as a set of linear equations was
put forwarded to determine the complex amplitude of the illumination and sample …

In nanoscale imaging technique and ultrafast laser, the reconstruction procedure is normally
formulated as a blind phase retrieval (BPR) problem, where one has to recover both the …

Blind diffuser-modulation ptychography has emerged as a low-cost technique for micro–
nano holographic imaging, which enables breaking the resolution limit of optical systems …

As the core task of the reconstruction in conventional ptychography (CP) and Fourier
ptychographic microscopy (FPM), the meticulous design of ptychographical iterative engine …

Ptychography, a relatively new form of phase retrieval, can reconstruct both intensity and
phase images of a sample from a group of diffraction patterns, which are recorded as the …
