Title (EN) LIQUID CRYSTAL BEAM CONTROL DEVICE AND MANUFACTURE
(FR) DISPOSITIF DE COMMANDE DE FAISCEAU À CRISTAUX LIQUIDES ET FABRICATION
Abstract:
(EN) Liquid crystal light beam control devices and their manufacture are described. Beneficial aspects of beam broadening devices employed for controlled illumination and architectural purposes are presented including improving beam divergence control, improving beam broadening dynamic range control, beam divergence preconditioning, improving projected beam intensity uniformity and reducing color separation in the projected beam. Both beam control devices having in-plane and homeotropic ground state liquid crystal alignment are presented.
(FR) La présente invention concerne des dispositifs de commande de faisceau de lumière à cristaux liquides et leur fabrication. L'invention concerne des aspects bénéfiques de dispositifs d'élargissement de faisceau utilisés pour des applications d'éclairage commandé et architecturales, comprenant l'amélioration de la commande de divergence de faisceau, l'amélioration de la commande de plage dynamique d'élargissement de faisceau, le préconditionnement de divergence de faisceau, l'amélioration de l'uniformité d'intensité de faisceau projeté et la réduction de la séparation de couleur dans le faisceau projeté. L'invention concerne à la fois des dispositifs de commande de faisceau ayant un alignement de cristaux liquides dans l'état fondamental planaire et homéotrope.
