Abstract
a presente de invenção se refere a um método para produzir um dispositivo óptico, de preferência, um dispositivo de segurança, incluindo as etapas de: formar uma estrutura de relevo plano em uma primeira superfície substancialmente plana de um substrato, de preferência, um substrato transparente, a estrutura de relevo plano tendo uma primeira direção de alinhamento e incluindo uma pluralidade de elementos de estrutura de relevo, cada um tendo a mesma altura; e aplicar uma camada de polímero de cristal líquido (lcp) na estrutura de relevo plano, de modo que a camada de lcp esteja alinhada com a estrutura de relevo, em que a camada de lcp inclui pelo menos uma ou mais primeiras regiões de lcp com uma primeira altura e uma ou mais segundas regiões de lcp tendo uma segunda altura acima da primeira superfície substancialmente plana do substrato, em que a segunda altura é diferente da primeira altura; e um dispositivo óptico formado por tal método.
