Title (EN) OPTICAL SYSTEM, METHOD, AND APPLICATIONS
(FR) SYSTÈME OPTIQUE, PROCÉDÉ ET APPLICATIONS
Abstract:
(EN) An electrically controllable optical imaging system (and associated methods) in which a liquid crystal (LC) panel (without polarizers or color filters) is utilized to control the input light polarization from a polarized display device. Different polarization states lead to different path lengths in the proposed optical system that includes a polarization dependent component, which in turn results in different focal lengths or different image distances and magnifications upon electrically controlling the LC panel.
(FR) L’invention concerne un système d’imagerie optique à commande électrique (et des procédés associés), dans lesquels un panneau à cristaux liquides (LC) (sans polariseurs ni filtres de couleur) est utilisé pour contrôler la polarisation de la lumière entrante provenant d’un dispositif d’affichage polarisé. Différents états de polarisation conduisent à différentes longueurs de trajet dans le système optique de l’invention, qui comprend une composante dépendante de la polarisation, laquelle produit à son tour des distances focales différentes ou des distances d’image et agrandissements différents lorsque le panneau LC est commandé électriquement.
