Abstract

A method for non-invasive observations of a fundus using an ophthalmoscope is provided. The method includes illuminating a retinal region of an eye by projecting an illumination pattern of illumination light onto the retinal region, at least one of detecting a portion of fluorescent light emitted from the retinal region and detecting a portion of illumination light reflected from the retinal region, thereby capturing a series of images of the retinal region at a plurality of different relative positions of the retinal region with respect to the illumination pattern projected onto the retinal region, wherein between the capturing of at least two images of the series the relative position of the retinal region with respect to the illumination pattern projected onto the retinal region is shifted in a non-controlled manner, and processing the captured images to extract a sub-resolution image of the retinal region.
