When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

X-ray ptychographic microscopy combines the advantages of raster scanning X-ray
microscopy with the more recently developed techniques of coherent diffraction imaging. It is …

Ptychography is a form of phase imaging that uses iterative algorithms to reconstruct an
image of a specimen from a series of diffraction patterns. It is swiftly develo** into a …

Traditional imaging systems exhibit a well-known trade-off between the resolution and the
field of view of their captured images. Typical cameras and microscopes can either “zoom in” …

Fourier ptychography is a new computational microscopy technique that provides gigapixel-
scale intensity and phase images with both wide field-of-view and high resolution. By …

Both high resolution and high precision are required to quantitatively determine the atomic
structure of complex nanostructured materials. However, for conventional imaging methods …

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 …

Recent advances in high-speed pixelated electron detectors have substantially facilitated
the implementation of four-dimensional scanning transmission electron microscopy (4D …

Phase engineering of nanomaterials (PEN) is an emerging field that aims to tailor the
physicochemical properties of nanomaterials by precisely manipulating their crystal phases …

Accurate knowledge of translation positions is essential in ptychography to achieve a good
image quality and the diffraction limited resolution. We propose a method to retrieve and …
