18 January 2005 High-speed spectral domain optical coherence tomography for imaging of biological tissues
Author Affiliations +
Optical coherence tomography (OCT) is a new modality used to image biological tissues that weakly scatter and absorb light. It was demonstrated that this technique provides image with micrometer resolution in a noncontact and noninvasive way. Traditional OCT is time domain OCT (TDOCT). In this method the length of the reference arm in an interferometer is rapidly scanned over a distance corresponding to the imaging depth range. The mechanism of scanning largely limits the acquisition speed and makes real-time imaging impossible. In recent years a new model OCT based on Fourier domain interferometry is emerged, we called it spectral OCT (SOCT) or Fourier domain OCT (FDOCT). SOCT can avoid scanning of the reference, thus can reach very high acquisition speed. In this paper, spectral OCT related theories and techniques are reviewed. This paper consists of three sections: principle of SOCT, different sep-ups, recent progress and advance.
