Abstract
The components of a fundus camera for observing an eye ()—namely, an illumination device () to illuminate an image field of the eyeground () and an image recording device () onto which the eyeground () is projected by means of a projection device ()—are positioned to be confocal. The illumination device () is so structured that a periodic light pattern is created against the eyeground () within the illuminated image field. Further, an offset medium is present to offset the pattern by less than one period. The image recording device () is connected to an evaluation unit () in order to combine at least three recordings illuminated with offset patterns into a single photograph. A single, unstructured, extremely sharply focused photograph of the eyeground () may thus be obtained.
