摘要： For the model-based determination of the biometry of eyes, the eye is illuminated by a light source via a scanning unit, the focus of the measuring light beam in the eye is moved or shifted laterally and/or axially via an adjusting device and the light fractions back-scattered by the boundary surfaces and from the tissue of the eye via an interferometer are detected by a sensor and relayed to a control and evaluation unit by which a parametric eye model which describes at least two boundary surfaces present in the eye is adapted to the scan or scans. The invention relates to the field of ophthalmology and serves in particular for the optical determination of the biometry of eyes by application of two-dimensional optical coherence tomography images. However, the method is not limited to the use of coherence tomography nor to the utilization of optical measurements.

摘要： The eye is illuminated by a variable laser light source with a measurement range corresponding to the eye length, wherein the focus of the laser beam in the eye can be shifted laterally and/or axially by an adjustment mechanism, and the light fractions back-scattered from the sample are captured via an interferometer by a data acquisition unit and forwarded to a data processing unit. In the data processing unit, an OCT whole-eye scan is combined with at least one or several further overlapping tomographic part-eye or whole-eye scans. Reference information is used to register the first whole-eye scan with the further part-eye or whole-eye scans, and the combined whole-eye scan is evaluated and/or displayed on a user surface.

摘要： Optimized device for swept source optical coherence domain reflectometry and tomography. In the coherence-optical device, light, with the aid of an interferometer, is used for distance-measuring and imaging purposes on reflecting and scattering areas of the human eye. The optimized device according to the invention consists of includes a tunable light source, matched to the sought-after measurement region ZOCT, with a resonator length LR, an interferometric measurement arrangement, a data capturing unit for capturing the light portions scattered back from the sample and a data processing unit. Here the resonator length LR of the tunable light source is matched not only to the sought-after measurement region ZOCT, but also to the entire interferometric measurement arrangement such that disturbance points present in the interferometric measurement arrangement cannot create disturbance signals in the sought-after measurement region ZOCT.

摘要： A system for determining the surface shape of the cornea of an eye by analyzing the reflection of a spatially distributed ring pattern. The system includes an element for generating a ring pattern, an illuminating unit, an image capturing unit, and a control and analyzing unit. The element for generating rings is a fresneled axicon with annular structures of different radii. Furthermore, an optical element for illuminating the entire surface of the fresneled axicon with plane waves and an optical element for separating the illuminating and detecting beam path are arranged between the illuminating unit and the fresneled axicon.

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： Systems and methods are described for imaging an eye portion or for treating glaucoma in an eye of a patient. In a first step an optical microscopic image of a portion of the eye is acquired. In the optical microscopic image a distinguishable anatomical structure is identified to predict a location of a volume portion to be imaged three-dimensionally. Three-dimensional imaging of the located volume portion is performed by acquiring an optical coherence tomography image of the located volume portion. The volume portion is treated by either directing a laser beam to the volume portion or inserting an implant based on the OCT-image.

摘要： An ophthalmological measuring system, for obtaining biometric data of an eye, provided with the necessary calibration and check devices for monitoring the functionality and the calibration status. The ophthalmological measuring system includes an illumination source for illuminating an eye with light and with a sensor for recording and analyzing back-scattered or reflected light components and a controller. At least one calibration and check system integrated in the ophthalmological measuring system for monitoring the functional and calibration status is provided. A device is also provided which houses the calibration and test structures and which reads off the individual physical data therefrom by an interface. The ophthalmological measuring system is in particular provided for determining biometrical data but can also be used for ophthalmological, dermatological or other devices which require calibration and/or functional checking at regular intervals.
