Time Multiplexing Super Resolving Technique for Imaging from a Moving Platform

Abstract:
The superposition of two coaxial Gaussian beams with offset foci and orthogonal linear polarizations can be used to produce a right- or leftcircular polarization component with a focal spot of volume smaller than that of the Gaussian beam. This polarization-assisted axial and transverse superresolution effect is attributed to the differential Gouy phase shift within the focal region or to the non-Gaussian annular distribution of the circularlypolarized components in the far field.

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...
