Abstract
There is provided an apparatus for recording a depth profile of a biological tissue, in particular a frontal eye section of a human eye, according to the principle of optical coherence tomography, comprising a light source adapted to generate a bundle of light rays, an interferometer arrangement having a beam splitter device adapted to spatially separate the bundle of light rays into a reference beam and a measurement beam directed toward the tissue, a reference beam deflection device adapted to deflect the reference beam, a beam superpositioning device adapted to spatially superimpose the deflected reference beam onto the measurement beam deflected by the tissue into a superpositioned beam, and a detector arrangement for detecting information in the superpositioned beam associated with the difference of the optical path length of the reference beam and the measurement beam.
