Abstract

abstract a security device comprises a transparent substrate (100) having an opacifying layer (102) disposed on at least one surface. a reflective grating layer (103) comprises one or more arrangements of grooves, and a liquid crystal material layer (114) is disposed over at least a portion of the grating layer. the arrangements of grooves have a groove spacing such that liquid crystal molecules within the liquid crystal material layer are substantially aligned so as to polarise optical radiation passing therethrough. the security device further includes apertures formed in the opacifying layer and the grating layer comprising a transmissive diffractive optical element (doe). the security device thereby comprises a transmissive security feature, visible when viewed in transmission mode by the naked eye, in combination with a covert, reflective security feature, visible only using a suitably oriented polariser. ------------------------------------------------------------------------------------------------- tradução do resumo resumo patente de invenção: "dispositivo de segurança com imagens ocultas". a presente invenção refere-se a um dispositivo de segurança que compreende um substrato transparente (100) que tem uma camada de opacificação (102) disposta sobre pelo menos uma superfície. uma camada gradeada refletora (103) compreende um ou mais arranjos de sulcos, e uma camada de material de cristal líquido (114) é disposta sobre pelo menos uma porção da camada gradeada. os arranjos de sulcos têm um espaçamento de sulco de tal modo que as moléculas de cristal líquido dentro da camada de material de cristal líquido sejam substancialmente alinhadas com a finalidade de polarizar a radiação óptica que atravessa as mesmas. o dispositivo de segurança inclui adicionalmente aberturas formadas na camada de opacificação e na camada gradeada que compreendem um elemento óptico difrativo transmissivo (doe). o dispositivo de segurança compreende, desse modo, um recurso de segurança transmissivo, visível quando visualizado em modo de transmissão a olho nu, em combinação com um recurso de segurança refletor oculto, visível apenas com o uso de um polarizador adequadamente orientado.
