Abstract
(EN)
An optical system includes a lens layer including a plurality of microlenses arranged along orthogonal first and second directions, and at least one optically opaque mask layer spaced apart from the lens layer and defining a plurality of through openings therein arranged along the first and second directions. There is a one-to-one correspondence between the microlenses and the openings, such that for each microlens, the microlens and corresponding openings are substantially centered on a straight line making a same oblique angle with the lens layer. An optical layer can include the lens layer and the optically opaque mask layer embedded in the optical layer.
(FR)
L'invention concerne un système optique comprenant une couche de lentille comprenant une pluralité de microlentilles disposées le long de première et seconde directions orthogonales, et au moins une couche de masque optiquement opaque espacée de la couche de lentille et définissant une pluralité d'ouvertures traversantes dans celle-ci disposées le long des première et seconde directions. Il existe une correspondance univoque entre les microlentilles et les ouvertures, de sorte que pour chaque microlentille, la microlentille et les ouvertures correspondantes sont sensiblement centrées sur une ligne droite formant un même angle oblique avec la couche de lentille. Une couche optique peut comprendre la couche de lentille et la couche de masque optiquement opaque incorporée dans la couche optique.
