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 …

We present a new label-free three-dimensional (3D) microscopy technique, termed transport
of intensity diffraction tomography with non-interferometric synthetic aperture (TIDT-NSA) …

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 …

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 …

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 …

We report a computational 3D microscopy technique, termed Fourier ptychographic
diffraction tomography (FPDT), that iteratively stitches together numerous variably …
