Abstract
An apparatus for carrying out an eye-related measurement on a person includes a device for generating a fixation target with a holographic element. To generate the fixation target, the holographic element is illuminated by a light source. As a result of the illumination, the fixation target arises as a virtual holographic object. The eye-related measurement is conducted on an eye or the eyes of the person fixating the fixation target. Information is conveyed to the person by switching between different fixation targets.
