Title (EN) OPTICAL TOMOGRAPHIC IMAGING APPARATUS AND IMAGING METHOD FOR AN OPTICAL TOMOGRAPHIC IMAGE
(FR) APPAREIL D'IMAGERIE TOMOGRAPHIQUE OPTIQUE ET PROCÉDÉ D'IMAGERIE POUR UNE IMAGE TOMOGRAPHIQUE OPTIQUE
Abstract:
(EN) Provided is an optical tomographic imaging apparatus capable of, when imaging a tomographic image of an object, monitoring an incident state represented by an incident position and an incident angle of a measuring beam group with respect to the object, causing the measuring beam group to form an image at a predetermined position of the object, and obtaining the tomographic image at high speed. The optical tomographic imaging apparatus is featured in that one of multiple beams emitted from a light source to be split and multiple beams emitted from multiple light sources are split into a measuring beam group and a reference beam group, and the optical tomographic imaging apparatus includes a monitoring device for obtaining a monitoring image of the object, thereby capable of monitoring an incident state represented by an incident position and an incident angle of the measuring beam group with respect to the object.
(FR) La présente invention concerne un appareil d'imagerie tomographique optique qui peut, lors de la formation d'une image tomographique d'un objet, surveiller un état incident représenté par une position incidente et un angle incident d'un groupe de faisceaux de mesure par rapport à l'objet, solliciter le groupe de faisceaux de mesure à former une image au niveau d'une position prédéterminée de l'objet et obtenir l'image tomographique à grande vitesse. L'appareil d'imagerie tomographique optique est caractérisé en ce qu'un des multiples faisceaux émis à partir d'une source de lumière devant être divisé et que plusieurs faisceaux émis à partir de plusieurs sources de lumière sont divisés en un groupe de faisceaux de mesure et en un groupe de faisceaux de référence, et l'appareil d'imagerie tomographique optique comprend un dispositif de surveillance servant à obtenir une image de surveillance de l'objet, ceci permettant de surveiller ainsi un état incident représenté par une position incidente et un angle incident du groupe de faisceaux de mesure par rapport à l'objet.
