Abstract
Official abstract text for this publication.
Systems and methods described herein employ multiple phase-contrast images with various relative phase shifts between light diffracted by a sample and light not diffracted by the sample to produce a quantitative phase image. The produced quantitative phase image may have sufficient contrast for label-free auto-segmentation of cell bodies and nuclei.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for phase contrast imaging of a sample comprising: a light source for illuminating the sample, wherein a first beam splitter generates from the light source at least a first beam of light and a second beam of light, wherein a first optical element is configured to collect light from the first beam of light that is not diffracted by the sample, and wherein a second optical element is configured to collect light from the second beam of light tha…
