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

The main obstacle in retrieving quantitative phase with high sensitivity is posed by the phase
noise due to mechanical vibrations and air fluctuations that typically affect any …

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 …

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 …

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

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 …

A cellular-level study of the pathophysiology is crucial for understanding the mechanisms
behind human diseases. Recent advances in quantitative phase imaging (QPI) techniques …

We demonstrate simultaneous phase and amplitude extraction from a single defocused
image of a homogeneous object. Subject to the assumptions explicitly stated in the …

The well-known transport of intensity equation (TIE) allows the phase of a coherent field to
be retrieved non-interferometrically given positive defined intensity measurements and …

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