Abstract:
As important analysis tools, microscopes with high spatial resolution are indispensable for scientific research and clinical diagnosis. We report a proof-of-principle experimental demonstration of a two-arm microscope scheme and show that, by measuring the second-order correlation of light fields, more details of an object can be obtained through recording more information about the initial illumination field. The effects arising from the transverse coherence length and the axial correlation depth of the illumination field are also discussed.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
