Polarized LED array microscope for single-shot quantitative phase imaging

Le résumé fourni par la source

Typical LED array microscopes require multiple image acquisitions for phase retrieval. Here, we propose a polarized LED array microscope for single-shot quantitative phase imaging with aberration correction. We implemented polarization-encoded illumination multiplexing by placing a custom-made polarization filter on top of the LED array. A single image was captured using a polarized sensor under polarized LED illumination. We reconstructed the quantitative phase by incorporating the polarization multiplexing model with a phase retrieval algorithm. We showed that the proposed technique can reconstruct aberration-corrected phase images with a single-shot intensity image.
