Title (EN) FRESNEL LENS WITH DYNAMIC DRAFT FOR REDUCED OPTICAL ARTIFACTS
(FR) LENTILLE DE FRESNEL À TIRAGE DYNAMIQUE POUR ARTEFACTS OPTIQUES RÉDUITS
Abstract:
(EN) A lens includes an optically transparent substrate having a first lens surface and a second lens surface opposite to the first lens surface. The first lens surface includes a plurality of Fresnel structures. A respective Fresnel structure of the plurality of Fresnel structures includes a slope facet and a draft facet. The respective Fresnel structure of the plurality of Fresnel structures is characterized by a representative pitch. The representative pitch of the respective Fresnel structure is based on a distance of the respective Fresnel structure from a reference axis of the lens. A display device that includes the lens and an electronic display coupled with the lens for outputting light through the lens and a method for transmitting light from an electronic display toward the lens are also described.
(FR) L'invention concerne une lentille comprenant un substrat optiquement transparent ayant une première surface de lentille et une seconde surface de lentille opposée à la première surface de lentille. La première surface de lentille comprend une pluralité de structures de Fresnel. Une structure de Fresnel respective parmi la pluralité de structures de Fresnel comprend une facette de pente et une facette de dépouille. La structure de Fresnel respective de la pluralité de structures de Fresnel est caractérisée par un pas représentatif. Le pas représentatif de la structure de Fresnel respective est basé sur une distance de la structure de Fresnel respective par rapport à un axe de référence de la lentille. L'invention concerne également un dispositif d'affichage qui comprend la lentille et un afficheur électronique couplé à la lentille permettant d'émettre de la lumière à travers la lentille et un procédé de transmission de lumière depuis un afficheur électronique vers la lentille.
