Abstract
A device for determining a movement of an eye includes an illumination unit by which optical radiation can be generated and emitted as an illumination ray bundle for illumination of at least one area of the cornea of the eye, a distance-determining unit, by which the illumination ray bundle returned as a detection ray bundle by the cornea can be received in a temporally resolved manner. A distance signal corresponding to a distance of the cornea from a reference plane can be generated using the received optical radiation of the detection ray bundle. the reference plane is defined relative to the distance-determining unit, and an evaluating unit, by which a position or movement signal corresponding to a position or movement of the eye can be generated using the distance signal.
