Abstract

L'invention concerne des systèmes d'imagerie et un procédé d'imagerie optique. Un exemple d'un système d'imagerie comprend un sous-système de balayage optique comprenant une source optique et un guide d'ondes, le guide d'ondes étant configuré pour diriger un rayonnement optique généré par la source optique sur une zone d'une scène, un sous-système de détection comprenant un capteur optique configuré pour recueillir un rayonnement optique provenant de la zone de la scène, et un ensemble de focalisation à fibres fusionnées comprenant un faisceau de fibres fusionnées, une pluralité de lentilles couplées ensemble et positionnées de façon à recevoir et à focaliser le rayonnement optique réfléchi en provenance de la zone de la scène directement sur le faisceau de fibres fusionnées, une réseau de microlentilles interposé entre le faisceau de fibres fusionnées et le capteur optique et positionné de façon à recevoir le rayonnement optique réfléchi provenant du faisceau de fibres fusionnées, et une lentille de focalisation positionnée de façon à diriger le rayonnement optique réfléchi provenant du réseau de microlentilles sur le capteur optique.
