摘要： The invention relates to the field of ophthalmology and serves for displaying the anterior and posterior portions of the eye, in particular the whole eye, wherein the displays are preferably based on optical coherence tomography scans. According to the invention, the eye is illuminated from 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. The main use of the present solution lies in ophthalmological diagnosis and therapy and in the preparation and the follow-up of surgical interventions.

摘要： A device for performing distance measurements on an eye. The device includes an interferometer, focuses at least one measurement beam records backscattered radiation and interferometrically generates a measurement signal displaying structures of the eye by time-domain, spectral-domain or Fourier-domain coherence reflectometry, has an adjustment apparatus for laterally and/or axially displacing the focus in the eye or for varying a polarization state of the measurement beam and has a control apparatus which actuates the interferometer, wherein the control apparatus generates a plurality of A-scan individual signals from the backscattered radiation, combines these to an A-scan measurement signal and actuates the adjustment apparatus for displacing the position of the focus or for varying the polarization while recording the backscattered radiation from which the control apparatus generates the A-scan individual signals is being recorded.

摘要： The invention relates to a spectrometer, especially for use in an optical coherence tomograph (1) for detecting parameters of the human eye, said spectrometer having an input for measurement radiation to be analyzed, fanning the measurement radiation spectrally out along a direction in a fan and guiding it onto a detector (8) that extends along the direction and that comprises a plurality of detector pixels that are sensitive to the measurement radiation. The spectrometer (2) has an adjusting element (5) which can be adjusted in a controlled manner to adjust the relative position of the fan and the detector (8), thereby optimizing the incidence position of the fan on the detector (8). The invention is characterized in that the detector (8) has at least two superimposed, adjacent pixel lines and that a control device (9) reads out the superimposed pixels of a plurality of pixel lines in a combined manner for a spectral analysis of the measurement radiation in a pixel binning and evaluates signal differences between superimposed pixels to control the adjusting element (5) and to center the incidence position of the fan at a right angle to the direction of the pixel lines.

摘要： A line scan imager is used to determine the motion of a subject. Each line of image data from the line scan imager is compared with a reference image. The location of a matching line in the reference image reveals the displacement of the subject. The current subject displacement can be determined based on each line of image data. The resulting displacement information can be used to correctly place other optical beams on the subject. The method can be applied to tracking the human eye to facilitate measurement, imaging, or treatment with a beam of optical radiation.
