The ability to characterize the Point Spread Function (PSF) is crucial in practical microscopy,
but requires knowledge of the complex PSF for approaches that detect fields instead of …

Refractive index imaging is a label-free technique that enables long-term monitoring of the
internal structures and molecular composition in living cells with minimal perturbation …

We present a phase-shifting interferometric technique for imaging live biological cells in
growth media, while optimizing spatial resolution and enabling potential real-time …

Phase contrast imaging is a specific technique in optical microscopy that is able to capture
the minute structures of unlabeled biological sample from contrast generated in the …

Interferometric phase measurements of wide-field images of biological cells provide a
