Title (EN) FULL-FIELD OPTICAL COHERENCE TOMOGRAPHY SYSTEM FOR IMAGING AN OBJECT
(FR) SYSTÈME DE TOMOGRAPHIE PAR COHÉRENCE OPTIQUE PLEIN CHAMP PERMETTANT D'IMAGER UN OBJET
Abstract:
(EN) The present invention relates to a full-field optical coherence tomography system (300) for imaging an object (319), comprising a light source (301), a first interferometric device having means for splitting an input light beam and comprising at least a reflecting surface (307), a second interferometric device having means for splitting the spectrally modulated output beam and comprising at least a reflecting surface, a multichannel acquisition device (321), the system (300) being characterized in that at least one of the interferometric devices includes at least a focusing optical element arranged to focus at least one of the input beams or at least one of the output beams onto the corresponding reflecting surface of the corresponding interferometric device.
(FR) La présente invention concerne un système de tomographie par cohérence optique plein champ (300) permettant d'imager un objet (319) et comprenant une source de lumière (301), un premier dispositif interférométrique comportant un moyen conçu pour diviser un faisceau lumineux d'entrée, et au moins une surface réfléchissante (307), un second dispositif interférométrique comportant un moyen conçu pour diviser le faisceau de sortie à modulation spectrale, et au moins une surface réfléchissante, ainsi qu'un dispositif d'acquisition à canaux multiples (321). Le système (300) est caractérisé en ce qu'au moins un des dispositifs interférométriques contient au moins un élément optique de focalisation conçu pour focaliser au moins un des faisceaux d'entrée ou au moins un des faisceaux de sortie sur la surface réfléchissante correspondante du dispositif interférométrique correspondant.
