摘要： A fundus camera for the recording of high-resolution colour 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.

摘要： The present invention is directed to a device and a method for the observation, documentation and/or diagnosis of the fundus in which the diagnosis is carried out by evaluating the documented images of the fundus. The device according to the invention comprises an ophthalmological examination device, a multi-spectral sequential illumination module, an image recording module, a control and safety module, and an evaluating unit. The illumination module which is connected to the ophthalmologic examination device has at least two individual light sources and which can be regulated individually with respect to intensity and duration and which emit monochromatic light of different wavelengths. The light coming from the illumination module is imaged on the image recording module from the ophthalmologic examination device by the eye being examined. The control and safety module controls the chronological sequence, duration and intensity of the individual light sources and monitors the light stress. An evaluating unit evaluates the recordings of the fundus transmitted by the image recording module. The inventive solution serves to record monochromatic images of the retina, for example, red, green, blue, or also infrared, and to record fluorescence images.

摘要： The invention refers to a process for determining the focus position when imaging a specimen (4) with a field stop imaged onto the specimen detecting this image using a position-sensitive receiving-device inclined relative to the field stop defining the focus position by means of intensity distribution in the receiving device. The invention also refers to set-ups as regards implementation of the process according to the invention. According to the invention, in a process of the above-mentioned type, imaging of the field stop onto the specimen (4) is at least partially superposed by an optical lattice; the position-sensitive receiving device is used to determine intensity values for the light reflected by the specimen; these intensity values are assigned to positions in the receiving device; position-related contrast values are determined from the position-related intensity values; the position of the contrast focus in the receiving device as equivalent of the current focus position is determined using these contrast values.
