Abstract:
The quality of retinal images is compromised by aberrations that remain uncorrected even in confocal adaptive optics imaging. This study demonstrates phase diversity (PD), a computational imaging technique, to address residual aberrations and enhance image quality in adaptive optics scanning laser ophthalmoscopy (AOSLO). By using images of the same object obtained with and without deliberately added aberrations, PD computes and compensates for the effects of existing residual aberrations beyond those corrected by a closed-loop AO system. Experimental validation demonstrates that PD improves visualization of retinal microstructures, including cone mosaics and dendrites of fluorescently labeled retinal ganglion cells (RGCs).

01:26Phase 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...
