A Fourier-domain optical coherence tomography (OCT) imager is presented. An OCT imager according to the present invention can have an auto-alignment process. The auto-alignment process automatically adjusts at least one optical component of a spectrometer of the imager so that the spectrometer is aligned during an imaging session. In addition to the auto-alignment process, OCT spectra are normalized for background spectra and for noise characteristics in order to provide a more accurate and clear OCT image.

L'invention porte sur un imageur de tomographie à cohérence optique (OCT) à domaine de Fourier à auto-alignement. Le procédé d~auto-alignement règle automatiquement l~un au moins des composants optiques du spectromètre de l~imageur qui se trouve donc aligné pendant les sessions d~imagerie. Outre le procédé d~auto-alignement, les spectres d~OCT sont normalisés en ce qui concerne les spectres de fond et les caractéristiques de bruit, ce qui permet d~obtenir une image plus précise et plus claire.
