Abstract[English]
A holographic device and method of forming a holographic device for a virtual retinal display, the holographic device comprising: a transparent substrate; and a holographic element arranged on said substrate; wherein the holographic element comprises a phase pattern and said phase pattern is a predefined optical coma configured and arranged to diffract light from a light source to form a plurality of images at an image plane of the holographic element. A virtual retinal display comprising a holographic device. An augmented reality system comprising a virtual retinal device and a pair of smart glasses.[French]
L'invention concerne un dispositif holographique et un procédé de formation d'un dispositif holographique pour un affichage rétinien virtuel, le dispositif holographique comprenant : un substrat transparent ; et un élément holographique disposé sur ledit substrat ; l'élément holographique comprenant un motif de phase et ledit motif de phase étant un coma optique prédéfini configuré et conçu pour diffracter la lumière provenant d'une source de lumière pour former une pluralité d'images au niveau d'un plan d'image de l'élément holographique. L'invention concerne également un affichage rétinien virtuel comprenant un dispositif holographique. L'invention concerne également un système de réalité augmentée comprenant un dispositif rétinien virtuel et une paire de lunettes intelligentes.
