000117745 520__ $$aOptical Coherence Tomography (OCT) is an imaging technique  with high axial resolution in the micro-meter-scale range  combined with a high sensitivity allowing for example to    probe weakly back-scattering structures beneath the   surface of biological tissues up to several millimeters. A   major improvement of this conventional technique represents  Fourier Domain OCT with a further decrease in image  acquisition time and additional sensitivity. The apparatus   including appropriate signal processing reconstructs the  depth profile from the spectrally resolved light signal  generated by a broadband source and an interferometric  imaging system. By frequency shifting the light fields with  frequency shifting means in the reference and sample arm a  phase resolved signal at high speed can be registered.  Therefore the reference arm does not rely on arm length  changes or delays. The beating signal generated in this way  shows high phase stability. The phase of this beating  signal is not wavelength dependent, as the frequency shift  applied is the same for all wavelengths. Moreover this  results in an additional suppression of unwanted auto- correlated distortion as well as an extended depth range.
