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) is a label-free, wide-field microscopy approach with
significant opportunities for biomedical applications. QPI uses the natural phase shift of light …

This Roadmap article on digital holography provides an overview of a vast array of research
activities in the field of digital holography. The paper consists of a series of 25 sections from …

Cell refractive index is a key biophysical parameter, which has been extensively studied. It is
correlated with other cell biophysical properties including mechanical, electrical and optical …

We report a technique for quantitative three-dimensional (3D) map** of refractive index in
live cells and tissues using a phase-shifting laser interferometric microscope with variable …

The approximately 120 MDa mammalian nuclear pore complex (NPC) acts as a gatekeeper
for the transport between the nucleus and cytosol. The central channel of the NPC is filled …

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

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 …

Digital holographic microscopy enables a quantitative phase contrast metrology that is
suitable for the investigation of reflective surfaces as well as for the marker-free analysis of …

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