摘要： A system includes an optical system having two beam splitters (a dichroic beam splitter and a polarizing beam splitter), which are designed to provide three separate beam paths for observing an object. The dichroic beam splitter is designed to separate two beam paths depending on the wavelength of the light of the respective beam path. The polarizing beam splitter is designed such that two beam paths are separated depending on a direction of polarization of the light of the respective beam path. The measuring light is linearly polarized after having passed the polarizing beam splitter and may be influenced with respect to the state of polarization by a retarding plate. The returning measuring light incident on the polarizing beam splitter is linearly polarized and also polarized in such a direction that the returning measuring light is transported through the polarizing beam splitter towards the analyzing detector with a high efficiency.

摘要： The present invention makes it possible to make high-quality recordings of the anterior and/or posterior segments of the eye as an individual image or also as a sequence of images without increasing the radiation load on the eye to be examined. In the method according to the invention, at least one pre-flash is used in order to determine an optimal exposure time for the main flash based on the recording of the pre-flash which is reflected by the object to be recorded. Both the pre-flash and the main flash are controllable and the recordings of the pre-flash and main flash are recorded with the same sensor of the electronic camera and are evaluated electronically by a control unit, and the recording of the main flash and, as the case may be, of the pre-flash is analyzed and/or corrected and displayed to the user.

摘要： The invention relates to a solution for interferometrically measuring the eye length and the anterior eye segment after the optical axis of the measuring system has been aligned with the optical axis of an eye. The device according to the invention for interferometrically measuring the eye length and the anterior eye segment consists of an illumination source, at least one interferometric measuring array with external reference, diverse optical imaging systems, and a control and evaluation unit. The illumination source has high spatial coherence and low coherence of time. Preferably, light is emitted by the illumination device from the NIR range, having a wavelength of 700-1000 nm, for example. Furthermore, an optical imaging system is arranged in front of the eye such that the illumination light impinges on the eye as a nearly collimated beam.

摘要： An SS OCT interferometry device for measuring a sample, in particular from an eye. The device interferometrically generates a measuring signal and from the signal a depth-resolved contrast signal of the sample by spectral tuning of the central wavelength of the measurement radiation of a measuring signal, and has a control unit for this purpose. The device includes a sample motion detector, which provides a motion signal indicating movement of or in the sample, the control unit uses the motion signal to correct the measuring signal with respect to measuring errors that are caused by a movement of or in the sample before or during the generation of the depth-resolved contrast signal.

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： A fundus camera for the recording of high-resolution color images of the fundus of non-dark-adapted eyes, and without the use of a mydriatic. The fundus camera has a strip-shaped pupil division, and includes a coherent or incoherent illumination source with illumination optics, a deflection mirror and an ophthalmoscope lens for illuminating the eye, detection optics and a detector for detecting the light reflected by the eye, and a control and evaluation unit. The deflection mirror has a strip shape, and the spatially resolving detector can be activated and read out in sectors. The control and evaluation unit connects the data read out in sectors in the form of a bright image from the detector and produce a resulting fundus image. The fundus camera records images of the fundus when the eyes are not dark-adapted for this purpose and no mydriatic has been used.
