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

Phase unwrap** is an important but challenging issue in phase measurement. Even with
the research efforts of a few decades, unfortunately, the problem remains not well solved …

For quantitative phase imaging (QPI) based on transport-of-intensity equation (TIE), partially
coherent illumination provides speckle-free imaging, compatibility with brightfield …

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 …

Deep neural networks have emerged as effective tools for computational imaging, including
quantitative phase microscopy of transparent samples. To reconstruct phase from intensity …

We demonstrate 3D phase and absorption recovery from partially coherent intensity images
captured with a programmable LED array source. Images are captured through-focus with …

The transport of intensity equation (TIE), a noninterferometric method for quantitative phase
imaging (QPI), enables the characterization of transparent objects and is widely applied in …

Quantitative phase imaging (QPI) recovers the exact wavefront of light from intensity
measurements. Topographical and optical density maps of translucent microscopic bodies …

The phase information of a complex field is routinely obtained using coherent measurement
techniques as, eg, interferometry or holography. The obtained measurement result is subject …

In order to realize high contrast imaging with portable devices for potential mobile
healthcare, we demonstrate a hand-held smartphone based quantitative phase microscope …
