Abstract

a presente invenção se refere aos métodos e aparelhos para criar imagens de formas sobrepostas por camadas base e de revelação de grades de microlentes. as imagens em forma sobreposta formam uma mensagem reconhecível por um observador humano ou por um dispositivo de computação e aquisição de imagem, tal como um smartphone. as imagens das formas sobrepostas podem ser criadas por diferentes técnicas sobrepostas que variam de técnicas de sobreposição por moiré 1d, moiré 2d e moiré de linha de nível até técnicas de sobreposição por deslocamento de fase e imagem lenticular. as técnicas de sobreposição por moiré permitem criar imagens de formas sobrepostas em diferentes níveis de profundidade aparente. as aplicações compreendem a proteção de documentos e artigos valiosos contra falsificações, a criação de anúncios atraentes, bem como a decoração de edifícios e exposições.
