Abstract:
1. A method for obtaining a Fourier domain OCT ray tracing at an eye comprising the steps of: illuminating a pupil of the eye at a plurality of reference points by a short-coherence illumination source and superimposing a measurement beam reflected at the reference points by interfaces and surfaces of the eye with a reference beam; spectrally splitting measurement data of the reference points at an output of an interferometer and imaging the measurement data on a two-dimensional detector array for the simultaneous readout of two-dimensional spectral-interferometric data and two-dimensional spatial data at the output of the interferometer; and conveying the measurement data to a control unit which determines the depiction of a three-dimensional spatial structure of all refracting and/or reflecting intraocular interfaces and surfaces of the eye based on the reference points which have been determined by spectral interferometry.
