Abstract[English]
The present invention relates to a method for preparing an optical metal oxide layer, to a formulation for preparing an optical metal oxide layer and to an optical device comprising an optical metal oxide layer. The optical metal oxide layers are particularly suitable for optical applications and may be used in optical devices such as, for example, in diffractive gratings for augmented reality (AR) and/or virtual reality (VR) devices.[French]
La présente invention concerne un procédé de préparation d'une couche d'oxyde métallique optique, une formulation pour la préparation d'une couche d'oxyde métallique optique et un dispositif optique comprenant une couche d'oxyde métallique optique. Les couches d'oxyde métallique optiques sont particulièrement appropriées pour des applications optiques et peuvent être utilisées dans des dispositifs optiques tels que, par exemple, dans des réseaux de diffraction pour réalité augmentée (RA) et/ou des dispositifs de réalité virtuelle (RV).
