The invention relates to a full-field OCT method for generating an imaging of an ocular fundus (), in which short-coherent light () is emitted and split into an object beam path () and a reference beam path (). The object beam path () is directed onto the ocular fundus (). The reference beam path () and a portion of the object beam path () reflected by the ocular fundus () are directed onto an image sensor (), such that an interference between the reference beam path () and the object beam path () occurs on the image sensor (), wherein the reference beam path () impinges on the image sensor () at an angle deviating from the object beam path (). Before impinging on the image sensor (), the reference beam path () impinges on an optical correction element () in order to reduce a chromatic aberration within the reference beam path (). Intensity information and phase information is determined from a capturing of the image sensor. A focus-adjusted image of the ocular fundus is calculated. The invention also relates to a system that is suitable for carrying out said method. Images of the ocular fundus can be captured without the beam path being previously adapted to the refractive power of the eye lens.

Full-field OCT method and system for generating an imaging of an ocular fundus

The invention relates to a free-beam interferometric method for illuminating a sequence of sectional areas in the interior of the light-scattering object. The method makes it possible for the user to select a larger image field and/or a higher image resolution than previously possible with the occurrence of self-interference of the specimen light from a scattering specimen.

Method for photocopying a sequence of cut surfaces inside a light-scattering object with improved scanning

The invention relates to an interferometric method, in which the light scattered by an object is imaged onto an electronic camera, wherein a sample light component is assigned to scattering sites on a sectional face in the interior of the object. This sample light component can be separated from the contributions of the other sample light components by processing of the camera image and leads to a sectional image. A particular advantage of the invention lies in the fact that multiple parallel sectional faces can be exposed sequentially at predetermined intervals from each other in the interior of the object. Such a sequence of sectional images can be used to calculate a solid model of the object.
