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 …

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

Quantitative phase imaging (QPI) has emerged as a valuable tool for biomedical research
thanks to its unique capabilities for quantifying optical thickness variation of living cells and …

Fourier Ptychography is a new computational microscopy technique that achieves gigapixel
images with both wide field of view and high resolution in both phase and amplitude. The …

Image stacks provide invaluable 3D information in various biological and pathological
imaging applications. Fourier ptychographic microscopy (FPM) enables reconstructing high …

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 …

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” …

Optical imaging has served as a primary method to collect information about biosystems
across scales—from functionalities of tissues to morphological structures of cells and even at …

We demonstrate a new computational illumination technique that achieves a large space–
bandwidth–time product, for quantitative phase imaging of unstained live samples in vitro …

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 …
