Title (EN) OPTICAL COHERENCE TOMOGRAPHY APPARATUS AND METHOD WITH SPECKLE SUPPRESSION
(FR) APPAREIL ET PROCÉDÉ DE TOMOGRAPHIE PAR COHÉRENCE OPTIQUE AVEC SUPPRESSION DES TACHES
Abstract:
(EN) The invention relates to an optical coherence tomography apparatus and method. It improves speckle suppression by modifying the scanning trajectory (18) of the probing light beam so that groups of A scans close to the imaged segments (22) can be recorded and averaged. The invention facilitates effective speckle suppression combined with high resolution and little dependence of sample motions during the measurement.
(FR) La présente invention concerne un appareil et un procédé de tomographie par cohérence optique. La suppression des taches est améliorée par modification de la trajectoire de balayage (18) du faisceau lumineux de sondage de telle sorte que les groupes de balayages A à proximité des segments imagés (22) puissent être enregistrés et que leur moyenne puisse être calculée. La présente invention facilite une suppression efficace des taches ainsi qu'une résolution élevée et une faible dépendance des mouvements des échantillons pendant la mesure.
