High-spatiotemporal-resolution quantitative phase microscopy under unmatched illumination.
Diffraction-based quantitative phase microscopy (QPM) conventionally requires stringent numerical aperture (NA) matching between illumination and objective lens (OL). We propose high-spatiotemporal-resolution QPM under unmatched illumination (HSR-QPM-UI) that fully eliminates this constraint. By introducing a 0.5π phas...
