Abstract

L'invention concerne un système de tomographie par cohérence optique d'imagerie parallèle. Selon un mode de réalisation, le système comprend une source de lumière, une unité de balayage mobile et un interféromètre comportant un bras de référence et un bras à échantillon. L'unité de balayage comprend une pluralité d'ouvertures éclairées par une lumière incidente provenant de la source de lumière. L'unité de balayage produit une pluralité de faisceaux de lumière transmis à l'interféromètre. Chaque faisceau de lumière est divisé pour produire une pluralité de faisceaux de référence et d'échantillonnage. Les faisceaux d'échantillonnage sont balayés sur un échantillon et renvoient les signaux de lumière d'échantillonnage reflétée par le biais du bras à échantillon, combinés aux signaux de lumière de référence reflétée par le biais du bras de référence. Un motif d'interférence ainsi formé est détecté par un capteur d'images et traité de sorte à générer une image numérique de l'échantillon. Selon certains modes de réalisation, l'unité de balayage peut comprendre un réseau de microlentilles. L'invention concerne en outre un procédé de balayage connexe.
