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 …

This article presents the photonic crystal fiber (PCF) based surface plasmon resonance
(SPR) biosensor for early detection of malaria disease in humans by measurement of the …

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 …

Quantitative phase imaging (QPI) has emerged as a valuable method for investigating cells
and tissues. QPI operates on unlabelled specimens and, as such, is complementary to …

Quantitative phase imaging (QPI) is a label‐free computational imaging technique that
provides optical path length information of specimens. In modern implementations, the …

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 …

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

We present spatial light interference microscopy (SLIM) as a new optical microscopy
technique, capable of measuring nanoscale structures and dynamics in live cells via …
