Title (EN) METHOD AND APPARATUS FOR THE PRODUCTION OF POLARIZATION HOLOGRAMS
(FR) PROCEDE ET APPAREIL POUR LA PRODUCTION D'HOLOGRAMMES DE POLARISATION
Abstract: front page image
(EN)The present invention relates to a method for the production of polarization holograms wherein, in a first step, a phase holgram is calculated (1) and wherein, in a second step, the calculated hologram is transferred to a material carrier (5) comprising a substance in which oriented birefringence can be produced locally by light exposure. The invention further relates to an apparatus for the production of polarization holograms and the use of the polarization holograms according to the invention as data stores, security features or diffractive optical elements for performing conventional optical functions .
(FR)La présente invention concerne un procédé pour la production d'hologrammes de polarisation, un appareil pour la production d'hologrammes de polarisation et l'utilisation des hologrammes de polarisation selon l'invention en tant que magasins de données, caractéristiques de sécurité ou éléments optiques diffractifs pour exécuter des fonctions optiques classiques.
