    摘要: Disclosed are an ophthalmologic apparatus and a method for the contactless observation, examination, treatment, and/or diagnosis of an eye. The apparatus is structurally based on a fundus camera or an ophthalmoscope. The arrangement comprises an illumination beam path which extends from a first illumination source (BQ) to the eye and is fitted with a perforated mirror (LS) and imaging optics (AO), and an observation beam path that extends from the eye to a detector (D) via the imaging optics (AO) and through the perforated mirror (LS). The arrangement additionally comprises a beam path for scanning illumination which extends from a second illumination source (BQ) to the eye and is fitted with a scanning unit (SE), a lens (O), and a beam splitter (ST) in addition to the imaging optics (AO). The scanning unit (SE) that is arranged in the beam path for scanning illumination is designed as (an) electrostatically or/and galvanometrically driven bidirectional or unidirectional tilting mirror(s) (KS).

    摘要: The invention relates to a method for producing an image of a layer of an object (4) by means of a wide field optical element (5) on a resolving detector (6). According to the invention, the object (4) is illuminated in a focused manner on at least one object plane (3) having at least two binary illuminating patterns (26, 27; 33, 34) and for each illuminating pattern (26, 27; 33, 34), the corresponding images are detected. The illuminating patterns (26, 27; 33, 34) respectively comprise dark areas (27; 34) and light areas (26; 33), the light and/or the dark areas completely covering the object (4) when the illuminating pattern (26, 27; 33, 34) is superimposed. A layer image is determined from the detected images, said layer image comprising a partial segment that respectively reproduces a partial area of the object (4) that is arranged inside the light area of one of the used illuminating patterns such that said edges are arranged at a distance from the edges of the light area about at least one predefined minimum distance, and which are respectively determined with at least partial artificial light correction using at least two images which are respectively detected for different illumination patterns in which the partial area corresponding to the respective partial segment is arranged completely inside the light area of a first different illuminating pattern or completely inside a dark area of a second of the different illuminating pattern.

    摘要: The invention relates to a device for the observation, documenting and/or diagnosis of an eye, especially the front eye section, the iris, the lens, the glass body, and the eyeground. The homogeneously illuminating ophthalmological appliance consists of an illumination device provided with an illumination source (1), a homogenisation unit (2, 3, 5), and a projection device (7), at least one organic or inorganic radiation source with spectrally selective emission being used as an illumination source. The illumination generated in this way enables correspondingly adapted visual and/or digital observation, recording or display of the examined regions of the eye on a visualisation unit. For homogenisation purposes, the light emitted from the radiation sources (1) is collimated by means of a condenser lens (2) and imaged onto the microlens array (3) consisting of respectively opposing spherical surfaces (3.1 and 3.2) arranged at a distance (3.3) corresponding to the focal distance of the microlenses.
