Multimodal Volumetric Retinal Imaging by Oblique Scanning Laser Ophthalmoscopy (oSLO) and Optical Coherence Tomography (OCT)
Published on: August 4, 2018
Abstract:
We present experimental results of an imaging technique that uses as a local probe the optical field enhanced at the junction of a scanning tunneling microscope illuminated by a p-polarized laser beam. Images of highly oriented pyrolithic graphite, recorded at a constant height mode, show a lateral optical resolution of as much as 10 nm. Approach curves exhibit sensitivity on a subnanometer scale of the optical signal to the tip-sample distance, yielding the ultrahigh vertical resolution reached in the images.

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...
