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 …

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” …

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

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 …

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 …

First envisioned for determining crystalline structures, ptychography has become a useful
imaging tool for microscopists. However, ptychography remains underused by biomedical …

Fourier ptychographic microscopy (FPM) is a promising and fast-growing computational
imaging technique with high resolution, wide field-of-view (FOV) and quantitative phase …

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 …

Modern microscopes used for biological imaging often present themselves as black boxes
whose precise operating principle remains unknown, and whose optical resolution and price …

The incremental gradient approaches, such as PIE and ePIE, are widely used in the field of
ptychographic imaging due to their great flexibility and computational efficiency …
