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. Furthermore, the image capturing unit consisting of an imaging system and an image sensor is designed for a telecentric distance-independent image detection.

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 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.
