Abstract

<B>''MéTODO DE TESTE DE DOCUMENTOS COM CAMADAS DE SEGURANçA EFETIVA DE DIFRAçãO óPTICA E APLICAçãO DO MESMO''<D> Esta invenção relaciona-se a um método de teste de documentos e sua aplicação. Até agora, documentos com camadas de segurança efetiva de difração óptica, em particular hologramas, tem sido testados com equipamento de teste óptico caro. O processo inteiro de teste leva tanto tempo que estes procedimentos de teste não podem ser usados em máquinas de processamento em alta velocidade. Rápida testabilidade é outro estágio de segurança na validação de camadas de segurança efetiva de difração óptica como uma característica de autenticidade. A camada efetiva de difração óptica tem uma camada de metalização descontínua e/ou camadas parcialmente metálico e/ou zonas de camadas metálicas em diferentes planos. Vários métodos de medição para determinar uma condutividade elétrica são conhecidos Na prática, o método de medição capacitiva sem contato tem demonstrado-se útil.
