Abstract: An apparatus for the observation and treatment of the eye with a laser, having an illumination light source, whose light is focussed on the part of the eye to be observed and which preferably contains a laser, a scanning device, which generates a scanning movement of the light of the illumination light source on the background of the eye, a detector device, which receives the reflected light, an evaluation and synchronization unit, which generates from the time-sequential signal output of the detector device a visual representation of the portions of the eye to be treated and shows the visual representation, on a monitor, and a treatment laser device, whose light can be reflected on the part of the eye to be treated. The apparatus provides that a visual representation in which the location or locations to be treated are marked, can be superimposed on the visual representation of the eye at least on the monitor, and a control unit aligns the laser to the marked location.

Abstract: Disclosed is an apparatus for aligning a focused beam of light and, in particular, a laser beam onto a surface using optical elements which image, respectively shape, deflect and align the beam of light.The present invention is distinguished by a deflecting optical element having, in addition, a focusing effect.

Abstract: Disclosed is an apparatus for examining objects having an illumination light source, the light of which can be focussed on the part of the object to be examined, a scanning device, which generates a scanning movement of the light beam from the illumination light source over the section to be examined and which is provided with beam-deflecting and beam-imaging optical elements, a sensor device, which receives the light reflected from said section to be examined, and an evaluation and synchronization unit, which produces an image of said section to be examined from the time-sequential output signal from said sensor device. The invented apparatus is distinguished by the fact that the optical axis of the examination and/or illumination beam can be shifted in a plane of said pupils in order to generate a stereoscopic image, and that the images produced with varying positions of the optical axes can be overlapped in order to produce a stereo image.

Abstract: An infrared fundus angiography camera and ICG angiography imaging procedure for improved visualization and diagnosis of vascular diseases of the eye, especially SRNV, features a narrow bandwidth non-coherent and decollimated infrared illumination source, an optical system for directing the infrared illumination onto the retina and for directing the resulting retinal image toward an image storage device, and an optical filter positioned between the retina and the image storage device for blocking the infrared illumination from entering the image storage device. An infrared laser produces infrared illumination and a opal glass, fiber array, or integrating sphere light diffuser positioned between the infrared laser and the optical system decollimates and makes the infrared illumination incoherent. The laser includes a temperature stabilized infrared laser diode having an output matched to the excitation peak of an infrared fluorescent dye, such as ICG.

Abstract: An apparatus for producing an image of an object and, in particular, for examining the eye, having an illumination light source, the light of which can be focussed onto the section of the object to be examined, a scanning device, which generates a scanning movement of the source of the illumination light over the section to be examined and which is provided with beam-deflecting and image-forming optical elements, a detector device, which receives the light reflected from the section to be examined, and an evaluation and sychronization unit, which produces an image of the selected structures of the object from the time-sequential output signal from the detector device at least two image forming optical elements, which can be interchanged in order to alter the horizontal deflection angle, or image magnification in the horizontal direction, are provided in the beam path between the beam-deflecting elements.

Abstract: Disclosed is an apparatus for examining the field of vision, having a scanning device, which is provided with beam deflecting and beam imaging elements, via which the illumination light beam from an illumination light source is guided onto the region of the fundus oculi to be imaged and, if need be, the light reflected from the fundus oculi is guided to a detector device, from the time-sequential output signal of which an evaluation and synchronization unit generates an image of the scanned section by points, and having a control unit, which controls the intensity of the illumination light beam scanning the fundus oculi in such a manner that marks, respectively patterns, are projected onto a predeterminable region of the fundus oculi with predeterminable brightness, which the person under examination perceives, respectively does not perceive in the event of defects in the field of vision.

Abstract: An apparatus for producing images of an object and, in particular, for observing the rear portions of the eye by an illumination device, the light of which is focused on the object to be imaged and which preferably is provided with at least one laser. A scanning device, which produces a scanning motion of the light from the illumination device on the object to be imaged. A detector device has at least one detector which receives the light reflected from the object to be imaged an assessement and synchronization unit produces the image from the time-sequential output signal from the detector device.It is possible to gain essential ground-laying information about the object to be imaged, e.g. the fundus of the eye, by special types of illumination and/or the analysis of the scattered back light according to the most varied criteria.
