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 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 …

The dielectric tensor is a physical descriptor of fundamental light–matter interactions,
characterizing anisotropic materials with principal refractive indices and optic axes. Despite …

Quantitative phase imaging (QPI) is a label-free technique providing both morphology and
quantitative biophysical information in biomedicine. However, applying such a powerful …

Holotomography (HT) represents a 3D, label-free optical imaging methodology that
leverages refractive index as an inherent quantitative contrast for imaging. This technique …

Quantitative Phase Imaging (QPI) provides unique means for the imaging of biological or
technical microstructures, merging beneficial features identified with microscopy …

The dry mass and the orientation of biomolecules can be imaged without a label by
measuring their permittivity tensor (PT), which describes how biomolecules affect the phase …

The utilizations of microfluidic chips for single RBC (red blood cell) studies have attracted
great interests in recent years to filter, trap, analyze, and release single erythrocytes for …

The inverse scattering problem, whose goal is to reconstruct an unknown scattering object
from its scattered wave, is essential in fundamental wave physics and its wide applications …

We propose a physics-informed neural network (PINN) as the forward model for
tomographic reconstructions of biological samples. We demonstrate that by training this …
