Ptychography is a powerful computational imaging technique that transforms a collection of low-resolution images into a high-resolution sample reconstruction. Unfortunately, algorithms that currently solve this reconstruction problem lack stability, robustness, and theoretical guarantees. Recently, convex optimization algorithms have improved the accuracy and reliability of several related reconstruction efforts. This paper proposes a convex formulation of the ptychography problem.

A weighted optimization for Fourier Ptychographic Microscopy

Though the proposed method is both conceptually and computationally simple, it dramatically improves the quality of reconstruction and converges to a lower mean squared error value compared to the conventional optimization.

Sample Efficient Fourier Ptychography for Structured Data

Through a novel framework of recovery algorithms, it is shown that one can reconstruct high-resolution images (or video) from fewer samples, via simple and natural assumptions on the structure of the images ( or video), and demonstrate the validity of the claims through a series of experiments.

Iterative least-squares solver for generalized maximum-likelihood ptychography

Although ptychography does not require a precise knowledge of the illumination wavefront, common implementations rely upon assumptions such as accurate knowledge of the scan positions and constant

It is demonstrated that the choice of cost function plays a critical role, with amplitude-based cost functions performing better than intensity-based ones and a global Newton's method algorithm which is robust and accurate being proposed.

Sub-Diffraction Imaging Using Fourier Ptychography and Structured Sparsity

This work uses a novel technique called CoPRAM with some modifications, to recover sparse (and block sparse) images from sub-sampled pty-chographic measurements, and demonstrates experimentally that this algorithm performs better than existing phase retrieval techniques, in terms of quality of reconstruction, using fewer number of samples.

Elementary signals in ptychography.

A theoretical framework of ptychography is proposed, which is based on Gabor's notion of decomposition into elementary signals and the concept of frames, which can serve as a bridge between the experimental technique and the rich and well established mathematical disciplines of wavelets decomposition and spectrogram analysis.

A new F PM reconstruction framework with deep learning methods and a multiscale, deep residual neural network for FPM reconstruction is proposed, which is more robust under system aberrations such as noise and blurring compared with conventional methods.

System calibration method for Fourier ptychographic microscopy

A system calibration procedure to calibrate the mixed systematic errors simultaneously from an overall perspective, based on the simulated annealing algorithm, the LED intensity correction method, the nonlinear regression process, and the adaptive step-size strategy, which improves the robustness of FPM, relaxes the experiment conditions, and does not require any preknowledge, which makes the FPM more pragmatic.



A phase space model of Fourier ptychographic microscopy.

It is demonstrated that partial coherence uniquely alters both conventional ptychography's and FPM's captured data, but up to a certain threshold can still lead to accurate resolution-enhanced imaging through appropriate computational post-processing.

A pupil function determination algorithm, termed embedded pupil function recovery (EPRY), which can be incorporated into the Fourier ptychographic microscopy (FPM) algorithm and recover both the Fouriers spectrum of sample and the pupil function of imaging system simultaneously simultaneously is developed and tested.

Wide-field, high-resolution Fourier ptychographic microscopy

An imaging method, termed Fourier ptychographic microscopy (FPM), which iteratively stitches together a number of variably illuminated, low-resolution intensity images in Fourier space to produce a wide-field, high-resolution complex sample image, which can also correct for aberrations and digitally extend a microscope's depth-of-focus beyond the physical limitations of its optics.
