Paper Abstract

Quantitative phase imaging (QPI) provides unique access to cellular and subcellular structures with nanometer-scale sensitivity, making it a valuable tool for non-destructive, label-free imaging of biological samples. However, implementation of QPI typically involves a transmission-based geometry and requires thin samples, preventing use of QPI in many important clinical settings, including endoscopy. In this work we demonstrate a fiber-optic device, with epi-illumination, capable of providing quantitative phase information that is well suited for clinical endoscopy, among other biomedical applications.
