Motion-corrected Fourier ptychography.
Fourier ptychography (FP) is a recently proposed computational imaging technique for high space-bandwidth product imaging. In real setups such as endoscope and transmission electron microscope, the common sample motion largely degrades the FP reconstruction and limits its practicability. In this paper, we propose a novel FP reconstruction method to efficiently correct for unknown sample motion....
متن کاملLow Rank Fourier Ptychography
In this paper, we introduce a principled algorithmic approach for Fourier ptychographic imaging of dynamic, time-varying targets. To the best of our knowledge, this setting has not been explicitly addressed in the ptychography literature. We argue that such a setting is very natural, and that our methods provide an important first step towards helping reduce the sample complexity (and hence acq...
متن کاملDigital pathology with Fourier ptychography
Fourier ptychographic microscopy (FPM) is a recently introduced method of acquiring high-resolution, wide field of view (FOV) giga-pixel histology images. The FPM procedure first acquires a sequence of low-resolution images of a sample under variable-angle illumination. It then combines these images using a novel phase retrieval algorithm to improve the employed microscope's resolution beyond i...
متن کاملDiffraction tomography with Fourier ptychography.
This paper presents a technique to image the complex index of refraction of a sample across three dimensions. The only required hardware is a standard microscope and an array of LEDs. The method, termed Fourier ptychographic tomography (FPT), first captures a sequence of intensity-only images of a sample under angularly varying illumination. Then, using principles from ptychography and diffract...
متن کاملDiffraction tomography with Fourier ptychography: supplementary material
This document provides supplementary information for “Diffraction tomography with Fourier ptychography," http://dx.doi.org/10.1364/optica.3.000827. It analyzes the convergence of the Fourier ptychographic tomography (FPT) algorithm in the presence of noise, then examines the connection between the first Born approximation and the multi-slice model, and finally includes additional experimental r...
