Quantitative phase tomography

TL;DR: Digital holographic microscopy is applied to perform optical diffraction tomography of a pollen grain for the first time, with a precision of 0.01 for the refractive index estimation and a spatial resolution in the micrometer range.

TL;DR: The quantitative refractive index map can potentially serve as an intrinsic assay to provide the molecular concentrations without the addition of exogenous agents and also to provide a method for studying the light scattering properties of single cells.

TL;DR: A review of the areas in which ideas from coherent X-ray methods are contributing to methods for the neutron, electron and optical communities is presented in this article, along with associated experiments in materials science.

TL;DR: A new era in which strict coherence and interferometry are no longer prerequisites for quantitative phase imaging and diffraction tomography is highlighted, paving the way toward new generation label-free three-dimensional microscopy, with applications in all branches of biomedicine.

TL;DR: In this paper, the authors explore propagation through the Poynting vector and find two classes of phase, one of which is topological in origin, and even then only in specific well-defined circumstances.

TL;DR: A new method for the extraction of quantitative phase data from microscopic phase samples by use of partially coherent illumination and an ordinary transmission microscope is presented, able to recover phase even in the presence of amplitude modulation.

TL;DR: In this paper, phase jumps related to the interface between the matrix and the reinforcing phases of the composites are detected even when these phases show very similar x-ray attenuation, illustrating the potential of the technique for assessing damage in materials with improved resolution and sensitivity.

TL;DR: The advent of relatively inexpensive computers and digital image acquisition systems has now made possible the three-dimensional reconstruction of images taken from the optical microscope.
