Quantitative phase imaging (QPI) is a label-free, wide-field microscopy approach with
significant opportunities for biomedical applications. QPI uses the natural phase shift of light …

The competition between resolution and the imaging field of view is a long-standing problem
in traditional imaging systems—they can produce either an image of a small area with fine …

Transmission electron microscopes use electrons with wavelengths of a few picometers,
potentially capable of imaging individual atoms in solids at a resolution ultimately set by the …

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

Realizing high resolution across large volumes is challenging for 3D imaging techniques
with high-speed acquisition. Here, we describe a new method for 3D intensity and phase …

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 …

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 …

Coherent diffractive imaging is unique, being the only route for achieving high spatial
resolution in the extreme ultraviolet and X-ray regions, limited only by the wavelength of the …

We demonstrate a method to achieve high efficiency phase contrast imaging in aberration
corrected scanning transmission electron microscopy (STEM) with a pixelated detector. The …

Fourier ptychography is a recently developed imaging approach for large field-of-view and
high-resolution microscopy. Here we model the Fourier ptychographic forward imaging …
