Patent ID: 6922250

Claim:
A method for obtaining topograms and tomograms of the eye structure by many simultaneously recorded short coherence interferometric depth scans through transversely adjacent points in the pupil, comprising the steps of: providing an interferometer having a measurement arm, a reference arm, a reference beam and an output; carrying out a short coherence interferometric depth scan on the eye by a transversely expanded primary measurement image of spatially coherent or spatially partially coherent light sources in the measurement arm of the interferometer; generating a primary reference image of the spatially coherent or spatially partially coherent light source in the reference arm of the interferometer; imaging both primary images at the interferometer output in secondary, coincident images on one-dimensional or two-dimensional photo detector arrays for detecting the simultaneously occurring photoelectric depth scan signals from transversely adjacent pupil points; and dynamically focusing of the measurement image synchronous with the coherence window, wherein the short coherence interferometric depth scan is carried out by changing the optical length of the interferometer measurement arm by a retroreflector and the primary measurement image is formed in the eye by imaging the interferometer light source via an intermediate image by optics whose focal length corresponds approximately to the optical length of the schematic eye.
