Title (EN) PRISM-ENHANCED LENSES AND METHODS OF USING PRISM-ENHANCED LENSES
(FR) LENTILLES AMÉLIORÉES PAR PRISME ET PROCÉDÉS D'UTILISATION DE LENTILLES AMÉLIORÉES PAR PRISME
Abstract:
(EN) An electro-active lens is presented which utilizes a surface relief structures and an electro-active material, with a change in refractive index facilitating the change in optical properties. A molded structure and a liquid crystal are used to form a diffractive lens. In addition to the classical approach of utilizing diffractive optics and multiple Fresnel zones to form a lens, an additional structure is placed between Fresnel zones in order to improve the diffraction efficiency across the visible spectrum, and reduce chromatic aberration.
(FR) L'invention concerne une lentille électro-active qui utilise des structures à relief de surface et un matériau électro-actif, un changement d'indice de réfraction facilitant le changement des propriétés optiques. Une structure moulée et des cristaux liquides sont utilisés pour former une lentille de diffraction. Outre l'approche classique consistant à utiliser des optiques de diffraction et de multiples zones de Fresnel pour former une lentille, une structure supplémentaire est placée entre des zones de Fresnel afin d'améliorer le rendement de diffraction sur le spectre visible, et de réduire l'aberration chromatique.
