摘要：
0There is provided an apparatus (100 200) for recording a depth profile of a biological tissue in particular a frontal eye section (140) of a human eye according to the principle of optical coherence tomography comprising a light source (101) adapted to generate a bundle (102) of light rays comprising wavelengths in a predetermined wavelength range with a predetermined bandwidth () and comprising an operating wavelength () an interferometer arrangement having a beam splitter device (120) adapted to spatially separate the bundle of light rays generated by the light source into a reference beam (104 204) and a measurement beam (106) directed toward the tissue a reference beam deflection device (130 230) adapted to deflect the reference beam a beam superpositioning device (150) adapted to spatially superimpose the deflected reference beam onto the measurement beam deflected by the tissue into a superpositioned beam (108 208) and a detector arrangement (160 170 270) for detecting information in the superpositioned beam associated with the difference of the optical path length of the reference beam and the measurement beam. The predetermined wavelength range is a range from 300 nm to 500 nm preferably from 350 nm to 450 nm and more preferably next to 403 nm.
