Abstract
(EN)
The present invention relates to an optical device for augmented reality, comprising: an optical means for at least partially transmitting visible light; and a reflection part which is disposed at the surface of or inside the optical means so as to reflect, to the pupil of a user’s eye, image light exiting an image-emitting part and corresponding to an augmented reality image, wherein the reflection part is formed in an asymmetric shape which means a shape other than a point-symmetric shape, the point-symmetric shape refers to a shape in which when the reflection part is rotated about a specific point existing in the plane of the reflection part, the same shape is always maintained at all rotation angles, and the asymmetric shape refers to a shape other than the point-symmetric shape.
(FR)
La présente invention concerne un dispositif optique de réalité augmentée, comprenant : un moyen optique servant à transmettre au moins partiellement la lumière visible ; et une partie réfléchissante qui est disposée sur la surface du moyen optique ou dans ce dernier de manière à réfléchir, vers la pupille de l’œil d'un utilisateur, une lumière d'image sortant d'une partie d'émission d'image et correspondant à une image de réalité augmentée, la partie réfléchissante revêtant une forme asymétrique c'est-à-dire une forme autre qu'une forme à symétrie ponctuelle, la forme à symétrie ponctuelle faisant référence à une forme selon laquelle, lorsque la partie réfléchissante est mise en rotation autour d'un point spécifique existant dans le plan de la partie réfléchissante, la même forme est toujours maintenue à tous les angles de rotation, et la forme asymétrique faisant référence à une forme autre que la forme à symétrie ponctuelle.
