Abstract:
1. A device for detecting a spatial position of an optical axis of an eye of a human or animal subject and for centering a reference system in relation to the optical axis, including at least one light source emitting a parallel light beam bundle, a positioning region for the subject provided opposite the light source, means for the relative position orientation of the parallel light beam bundle in relation to the eye of the subject, and at least one detector unit for detecting reflection events caused in and on the eye by the parallel light beam bundle, wherein an analysis unit generates control signals on a basis of scattering and reflection events detected by the at least one detector unit, by which the means for relative position orientation are activated, the control signals being generated so that at least one reflection event and at least one scattered light event are to be brought into congruency in relation to a propagation direction of the parallel light beam bundle.
