Abstract

L'invention concerne un dispositif d'imagerie (100, 500) qui comprend : - une unité anamorphique (10) pour former une image virtuelle (VMG1) d'une région de visualisation cylindrique (SRF1), et - une unité de focalisation (20) permettant de former une image réelle (IMG1) de l'image virtuelle auxiliaire (VMG1), l'unité anamorphique (10) comprenant au moins deux lentilles réfractives (LNS11, LNS12) qui ont été sélectionnées de telle sorte que la puissance de réfraction horizontale (Px,C) du dispositif d'imagerie (100) est supérieure à 1,5 fois la puissance de réfraction verticale (Py,C) du dispositif d'imagerie (100), et l'unité anamorphique (10) est conçue pour former l'image virtuelle (VMG1) par réfraction de la lumière (B0k) reçue à partir de la région de visualisation cylindrique (SRF1) de telle sorte que le rapport de forme (Δϕ/ΔΦ) de l'image virtuelle (VMG1) soit inférieur au rapport de forme (Δϕ'/ΔΦ') de la région de visualisation (SRF1)
