Extraction of depth moments by exploiting the partial coherence of radiation

TL;DR

This paper introduces a novel tomography technique that extracts depth moments from partially coherent fields using only two in-line images, eliminating the need for sample or source rotation.

Contribution

The method leverages partial coherence and defocus holography to perform depth tomography with minimal data, advancing non-invasive 3D imaging.

Findings

Depth moments can be retrieved from two in-line images.

The method does not require sample or source rotation.

It utilizes partial coherence and defocus holography for tomography.

Abstract

We retrieve depth information (moments) of an object using partially coherent fields and defocus induced holographic contrast. Our analysis leads to a form of tomography that does not require sample or source rotation. The tomography method presented here is performed with only two in-line images.
