Abstract: In an information system and a method for providing information in correlation with light that is incident on an eye, a pair of spectacles includes a holographic element that is supported in front of the eye of a wearer of the spectacles. An optical scanning device detects light that is incident on the eye via the holographic element.

Abstract: A method and information system for capturing signals, for processing signals, and for providing signals at least partially based on, or bearing correlation to, the captured signals is disclosed. The information system includes a signal input unit, a wireless communication unit, and an output unit. The signal input unit (preferably an optical signal unit) is constructed and is positionable to capture signals associated with an eye. The output unit is constructed to provide information based on the captured signals or to provide information as a function of the captured signals or in correlation with the captured signals.

Abstract: In the following, the essential points are summarized again by means of groups of characteristics which each individually and in combination with one another characterize the invention specifically: 1. Information system for providing information in correlation with light incident on an eye, having a holographic element disposed in front of the eye, and an optical scanning device which detects light incident on the eye by way of the holographic element. 2. Information system according to Point 1, wherein the optical scanning device is at a fixed predetermined angular ratio with respect to the holographic element. 3. Information system according to Point 1 or 2, wherein the optical scanning device detects light which is refracted by the holographic element before it impinges on the eye and does not enter the eye. 4.

Abstract: A system and method for eye examination by scanning light scattered from an area of the retina and projecting light into the eye includes a scanner, a receiver unit, and a projection unit. The scanner is constructed and arranged to scan an area on the retina. The receiver unit is optically coupled to the scanner and constructed and arranged to capture light scattered back from the area of the retina. The projection unit is constructed to generate and optically couple a light configuration to the scanner for delivering the light configuration into the eye relative to the area of the retina, wherein the scanner, the receiver unit and the projection unit are cooperatively designed to analyse a patient's sight.

Abstract: An apparatus for recording the exterior retina reflex image of the human eye, has a scanning recorder. The beams of the exterior images pass through the spectacle glasses constructed on the inner side as vaulted, imaging, beam splitting mirrors. The scanning recorder for recording and detouring the parallel beam bundles exiting from the eye after backscattering by each spot on the retina, is a biaxial scanner. An opto-electronic detector receives the light bundles from the biaxial scanner for serial recording of the retina reflex image.
