Paper Abstract

Quantitative phase imaging systems enable label-free imaging of transparent bio-samples. Miniaturization of these imaging systems will extend their potentials in biomedical and diagnostic applications. Here, we demonstrate a novel quantitative phase gradient microscope using two multifunctional metasurface layers. Thanks to the multi-functionality and compactness of the dielectric metasurfaces, the device simultaneously captures three differential interference contrast images to retrieve a quantitative phase gradient image in a single shot. Imaging experiments with diverse phase samples verify the capability to capture quantitative phase gradient data, with low noise levels and single cell resolution.
