Abstract
An ophthalmologic imaging device includes an optical illumination system having a cornea aperture, an iris aperture, and a lens aperture and an split mark projection system for focusing on the fundus of the subject eye. A light source is controlled by a controller to emit light for being able to obtain at least two consecutive fundus images. An inner aperture image corresponding to the lens aperture is projected on the posterior surface of the lens. The controller controls the lens aperture so that for obtaining a second fundus image, the inner aperture image is projected at a position shifted relative to the optical axis of an optical observatory or imaging system from a position at which the aperture image is projected for obtaining a first fundus image.
