apparatus for recording a depth profile of a biological tissue and method for measuring a depth profile of a biological tissue

摘要

apparatus for recording a depth profile of a biological tissue, and method for measuring a depth profile of a biological tissue is provided an apparatus (100; 200) for recording a depth profile of a biological tissue, in particular a section of front eye (140) of a human eye according to the principle of optical coherence tomography, comprising a light source (101) adapted to generate a beam (102) of light rays comprising wavelengths within a given range. wavelength having a predetermined bandwidth (30 sym) and comprising an operating wavelength (sym), an interferometer arrangement having a beam splitting device (120) adapted to spatially separate the beam of light generated by the light source in a reference beam (104; 204) and a tissue-directed measuring beam (106), a reference beam deflection device (130; 230) adapted to deflect the reference beam, a beam overlay device (150) adapted to spatially overlap the deflected reference beam in the tissue deflected measuring beam to an overlapping beam (108; 208), and a detector array (160, 170; 270) for detecting overlapping beam information associated with the optical path length difference of the reference beam and the measuring beam. The predetermined wavelength range is from 300 nm to 500 nm, preferably from 350 nm to 450 nm and more preferably around 403 nm.
