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 …

Abstract In 1948, Dennis Gabor proposed the concept of holography, providing a pioneering
solution to a quantitative description of the optical wavefront. After 75 years of development …

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

Digital holographic microscopy (DHM), which combines digital holography with optical
microscopy, is a wide field, minimally invasive quantitative phase microscopy (QPM) …

Multiple scattering limits the contrast in optical imaging of thick specimens. Here, we present
gradient light interference microscopy (GLIM) to extract three-dimensional information from …

We introduce a microscopic method that determines quantitative optical properties beyond
the optical diffraction limit and allows direct imaging of unstained living biological …

We discuss unique features of lens-free computational imaging tools and report some of
their emerging results for wide-field on-chip microscopy, such as the achievement of a …

Digital holography is an emerging field of new paradigm in general imaging applications.
We present a review of a subset of the research and development activities in digital …

Microscopy is one of the main research and application areas of digital holography. Direct
access to the phase as well as amplitude profiles makes quantitative phase microscopy by …

We present a technique called white-light diffraction tomography (WDT) for imaging
microscopic transparent objects such as live unlabelled cells. The approach extends …
