Abstract:
(EN) The purpose of the present invention is to increase the data processing speed in an SS-OCT and an FD-OCT including the SS-OCT and, in particular, to process large-size data obtained by a receiving unit at a faster speed than the data obtaining speed, reconfigure a tomography image in real time, and provide the reconfigured image to a user. In order to achieve the purpose, according to one embodiment of the present invention, an optical coherence tomography (OCT) is disclosed. The OCT device includes: a light source unit emitting a coherent light; an interferometer unit generating an interference pattern from a sample measured by receiving incident light emitted from the light source unit; the receiving unit receiving the interference pattern emitted from the interferometer unit and converting the interference pattern into an electrical signal; and a processing unit creating an image from data obtained by the receiving unit, wherein the processing unit can group the obtained data into a plurality of data sets and process the plurality of data sets in parallel.
(FR) La présente invention vise à accroître la vitesse de traitement de données dans une tomographie à cohérence optique à source balayée (SS-OCT) et une tomographie à cohérence optique dans le domaine de Fourier (FD-OCT) comprenant la SS-OCT et, en particulier, à traiter des données de grande dimension obtenues par une unité de réception à une vitesse plus rapide que la vitesse d'obtention de données, reconfigurer une image de tomographie en temps réel et fournir l'image reconfigurée à un utilisateur. Afin d'atteindre le but, selon un mode de réalisation de la présente invention, la présente invention porte sur une OCT. Le dispositif OCT comprend : une unité de source lumineuse émettant une lumière cohérente ; une unité d'interféromètre générant un motif d'interférence à partir d'un échantillon mesuré par réception d'une lumière incidente émise par l'unité de source lumineuse ; l'unité de réception recevant le motif d'interférence émis par l'unité d'interféromètre et convertissant le motif d'interférence en un signal électrique ; et une unité de traitement créant une image à partir de données obtenues par l'unité de réception, l'unité de traitement pouvant regrouper les données obtenues en une pluralité d'ensembles de données et traiter la pluralité d'ensembles de données en parallèle.
(KO) 본 발명의 목적은 SS-OCT 및 SS-OCT를 포함하는 FD-OCT에서 데이터 처리 속도를 향상시키기 위한 것으로서, 수신부에서 획득한 대용량 데이터를 데이터 획득 속도보다 빨리 처리하여 실시간으로 단층 영상을 재구성하여 사용자에게 제공하는 것을 목적으로 한다. 위와 같은 목적을 달성하기 위해, 본 발명의 일 실시예에 따르면, 광 간섭 단층 촬영장치(Optical Coherence Tomography, OCT)가 개시될 수 있다. 상기 광 간섭 단층 촬영장치는 가간섭성 광을 발생시키는 광원부와, 상기 광원부에서 방출광을 입사받아 측정되는 샘플로부터 간섭무늬를 발생시키는 간섭계부와, 상기 간섭계부에서 조사되는 간섭무늬를 수신하여 전기적인 신호로 변환하는 수신부와, 상기 수신부에서 획득된 데이터를 영상화하는 처리부를 포함하고, 상기 처리부는 상기 획득된 데이터를 복수의 데이터 세트들로 그룹화하고, 상기 복수의 데이터 세트들을 병렬 처리할 수 있다.
