OPTICAL DEVICE FOR AUGMENTED REALITY APPLICATIONS AND METHOD FOR ITS FABRICATION

摘要

An optical device for augmented reality applications is described, comprising in combination a glass frame (2a, 2b) adapted to accommodate at least one display (6) configured for emitting digital images and at least one lens (10) of the glasses, disposed within the field of view of a user, adapted to convey the digital images towards the aforementioned field of view. The lens comprises a substrate (52) and a plurality of metal nano-structures (54a, 54b), arranged on the substrate (52) in a optical path that connects the display (6) with the field of view of the user, adapted to cause the reflection of the digital images emitted by the display towards the ocular axis of the user.
