Abstract

L'invention vise à proposer un dispositif d'imagerie. À cet effet, l'invention concerne un dispositif d'imagerie qui a une pluralité d'unités d'imagerie, chaque unité d'imagerie comprenant une lentille avant et un élément d'imagerie. Le contour de chaque lentille avant est sensiblement similaire à un polygone apte à constituer un polyèdre convexe lorsque la lentille avant est vue le long de la direction d'axe optique. La lentille avant est agencée de façon à correspondre à une surface constituant le polyèdre convexe. Les points de non-parallaxe de la pluralité d'unités d'imagerie correspondent sensiblement les uns aux autres.
