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” …

The simple and compact optics of lensless microscopes and the associated computational
algorithms allow for large fields of view and the refocusing of the captured images. However …

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

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 …

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

Metasurfaces have recently risen to prominence in optical research, providing unique
functionalities that can be used for imaging, beam forming, holography, polarimetry, and …

Replacing curved and bulky optical elements with thin and lightweight counterparts is a
persistent pursuit of the optical society. Metasurfaces, as two-dimensional artificial …

Synthetic aperture technique could effectively expand the passband and beyond the
diffraction limit of aperture. Macroscopic Fourier ptychography (FP) makes synthetic aperture …

We propose a physics-assisted deep neural network scheme in Fourier ptychographic
microscopy (FPM) using untrained deep neural network priors (FPMUP) to achieve a high …
