Title
(DE) VERFAHREN UND ANORDNUNG ZUM VERMESSEN DES VORDEREN AUGENABSCHNITTS
(EN) METHOD AND ARRANGEMENT FOR MEASURING THE FRONT SECTION OF THE EYE
(FR) PROCEDE ET DISPOSITIF PERMETTANT DE MESURER LA SECTION OCULAIRE ANTERIEURE
Abstract
(DE) Die Erfindung betrifft eine Anordnung und ein Verfahren zum Vermessen des vorderen Augenabschnitts mit interferometrischen Mitteln. Das Auge wird mit einem konvergenten Strahlenbündel beleuchtet und durch Erzeugen von Richtungs- und Akkomodationsreizen mittels eines in den Strahlengang eingespiegelten Displays zur optischen Achse der Messanordung ausgerichtet.
(EN) The invention relates to an arrangement and a method for measuring the front section of the eye with interferometric means. The eye is illuminated by an convergent bundle of rays and is directed towards the optical axis of the measuring arrangement by the production of directional and accommodational stimuli by means of a display reflected into the path of rays.
(FR) L'invention concerne un dispositif et un procédé permettant de mesurer la section oculaire antérieure à l'aide de moyens interférométriques. L'oeil est éclairé par un faisceau de rayons convergents et est aligné avec l'axe optique du dispositif de mesure, par production de stimuli de direction et d'accommodation au moyen d'un affichage réfléchi sur la trajectoire du faisceau.
