    摘要： There 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 (?0), 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.
