摘要： A stripe pattern of known distance is imaged on the ocular fundus by the imaging unit for opthalmological devices. This makes it possible to carry out absolute measurements of distances and objects at the ocular fundus with knowledge of the initial values serving as a basis. The imaging unit for opthalmological devices, particularly fundus cameras, according to the invention comprises a device for generating and imaging any, but a known, stripe pattern or line pattern on the retina of an eye to be examined, a camera for recording the stripe pattern or line pattern on the retina, and an evaluating unit for determining the distances on the retina. The imaging unit is constructed in such a way that the stripe pattern or line pattern to be imaged is coupled into the beam path between the opthalmological device and the eye to be examined. The use of an imaging unit of this kind as an accessory to opthalmological devices also expands the possibilities for its use in measurements at the ocular fundus. Although the proposed solution is particularly suited to fundus cameras, it can also be used for other opthalmological device.

摘要： The invention is directed to an optical system for a fundus camera for reflection-free opthalmoscopy having a beam path with refractive and reflective optical elements which are used substantially in common for illumination and observation or recording. An imaging mirror system substantially comprising a plurality of reflecting optical elements in the form of mirrors and is provided for illuminating and imaging the fundus. At least one optical element, for example, mirror, is formed as a freeform mirror with an imaging, reflecting freeform surface. The optical elements are arranged in a housing in a precisely defined position and attitude relative to one another in such a way that an imaging of the reflecting surfaces of the optical elements on the image of the imaged retina is prevented within a wide diopter range of the patient's eye to be examined.

摘要： The present invention is directed to a device for examining the eye, preferably the fundus of the eye, by an optical system and electronic sensors for image recording in different imaging scales. In the device according to the invention, at least two image recording sensors with different shape factors are swivelably arranged in the imaging plane of the device. These image recording sensors have optically active surfaces of different geometric sizes, an approximately identical number of pixels and preferably the same electronic control and evaluation. The invention described herein requires no additional objectives and the optical adjustment is limited to an individual rigid objective. An exact alignment of the image recording sensors in the imaging plane and manufacturing tolerances can be compensated by adapting the image section by means of software. It is particularly advantageous that the imaging scale is influenced without changing the optical parameters of the system.

摘要： 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. An illumination beam path extends from a first illumination source to the eye and is fitted with a perforated mirror and imaging optics, and an observation beam path extends from the eye to a detector via the imaging optics and through the perforated mirror. The arrangement additionally comprises a beam path for scanning illumination which extends from a second illumination source to the eye and is fitted with a scanning unit, a lens, and a beam splitter in addition to the imaging optics. The scanning unit 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).

摘要： The present invention is directed to an optoelectronic unit for directing the eye gaze of the patient during examination or documentation of the fundus of the eye. The solution according to the invention for internal eye gaze guidance in fundus cameras provides a spatial light modulator for generating the fixation mark comprising imaging optics by which the displayed fixation mark is imaged on the eye fundus by a semitransparent mirror arranged in an observation beam path and via a swivel mirror arranged in a documentation beam path. The spatial light modulator is connected by a control unit to an actuating element for positioning the fixation mark. The device, which is preferably provided for fundus cameras, can facilitate the diagnosis of diseases of the eye fundus in that the documented recordings can be exactly reproduced and therefore exactly compared. In particular, the tracking and presentation of the course of diseases can be improved in this way.
