20120083811 | Microkeratome system for the generation of a flap on the human eye - A microkeratome system for the generation of a flap on the human eye includes a plurality of functionally different, separately interchangeable components with, in each instance, at least one characteristic feature. In addition, the system includes a control unit for controlling the operation of the microkeratome system, the control unit having access to stored information that is representative of at least one predetermined combination of the characteristic features of at least a fraction of the components, and also an input device for entering information that is representative of a desired combination of the characteristic features of at least a fraction of the components. The control unit is adapted to compare the desired combination of features with the at least one predetermined combination of features and to bring about a predetermined response, depending on the result of the comparison. In this way, the user can have his/her attention drawn to risky combinations, without having to rely solely on the wealth of experience of the user in connection with the selection of the components. | 04-05-2012 |
20120083812 | Device for ophthalmic surgery - A device for ophthalmic surgery includes a vacuum-pump arrangement for generating a vacuum serving for fixing a suction ring to an eye, an evacuation-path system for transmitting the vacuum to an interface port which permits the separable attachment of a suction-ring instrumentarium including the suction ring, and also a control unit for controlling the vacuum-pump arrangement. In accordance with the invention, the device includes pressure-measuring components for measuring at least the vacuum pressure, the control unit adapted to ascertain a differential pressure between the measured vacuum pressure and an atmospheric pressure. The vacuum-pump arrangement is preferably operated at maximal pumping power in a test-operation mode with suction-ring instrumentarium not attached, in order to ascertain an optimally obtainable relative underpressure in the evacuation-path system. In this way, in the case of fluctuating altitudes of the location of use of the ophthalmic-surgery device and also in the case of fluctuating weather conditions (low pressure, high pressure) it can be ascertained at all times whether the achievable relative underpressure is sufficient. | 04-05-2012 |
20130163003 | Apparatus and method for optical swept-source coherence tomography - An apparatus for optical swept-source coherence tomography comprises a spectrally tuneable source for emitting coherent light, and a detector for acquiring the intensity of remitted light backscattered from an object irradiated with the coherent light of the source. Further, the apparatus comprises a control device, which is set up to control the light source and the detector in such a way that the detector performs intensity acquisitions in accordance with a defined number of measurements, while the light source is tuned, the control device further being set up, for the purpose of altering the measurement depth or/and the axial resolution of the tomography, to alter the defined number of measurements or/and a spectral measurement bandwidth, within which the detector performs the intensity acquisitions. | 06-27-2013 |

20140362384 | SPECTROSCOPIC INSTRUMENT AND PROCESS FOR SPECTRAL ANALYSIS - A spectroscopic instrument includes a first optical component for spatial spectral splitting of a polychromatic beam of light impinging onto the first optical component, an objective, which routes various spectral regions of the split beam of light onto differing spatial regions, and a sensor, situated downstream of the objective in the beam path of the beam of light, with a plurality of light-sensitive sensor elements. The sensor elements are arranged in the beam path of the split beam of light in such a manner that each sensor element registers the intensity of a spectral sector of the beam of light and the medians of the spectral sectors are situated equidistant from one another in the k-space, where k denotes the wavenumber. | 12-11-2014 |
20150042949 | PROCESS FOR OPTICAL COHERENCE TOMOGRAPHY AND APPARATUS FOR OPTICAL COHERENCE TOMOGRAPHY - In a process for optical coherence tomography a plurality of first OCT slice images, in each first slice image representing a different slice of an object, are recorded. Subsequently a reference figure that is representative of the three-dimensional contour of at least one structural feature of the object in a given three-dimensional coordinate system is ascertained by feature recognition of the at least one structural feature in the first slice images. Then a plurality of second OCT slice images, each second slice image representing a different slice of the object, are recorded. At least a fraction of the second slice images are displaced in the coordinate system until each second slice image is in feature overlap with the reference figure. Lastly, a set of three-dimensional OCT image data is generated at least from the feature-overlapped second slice images. | 02-12-2015 |
