Title (EN) PHOTOCHROMIC BACKGROUND LAYER FOR AUGMENTED REALITY IMAGE ENHANCEMENT
(FR) COUCHE D'ARRIÈRE-PLAN PHOTOCHROMIQUE POUR AMÉLIORATION D'IMAGE DE RÉALITÉ AUGMENTÉE
Abstract:
(EN) Embodiments described herein relate to a waveguide imaging structure. The waveguide imaging structure generally includes an input coupling region, a waveguide region, and an output coupling region. In certain embodiments, a photochromic material layer is disposed on an output coupling region of the imaging structure. Also described herein are methods and materials for forming the photochromic material layer.
(FR) La présente invention concerne, dans des modes de réalisation, une structure d'imagerie de guide d'ondes. La structure d'imagerie de guide d'ondes comprend généralement une région de couplage d'entrée, une région de guide d'ondes et une région de couplage de sortie. Dans certains modes de réalisation, une couche de matériau photochromique est disposée sur une région de couplage de sortie de la structure d'imagerie. L'invention concerne également des procédés et des matériaux pour former la couche de matériau photochromique.
