Abstract

UN HOLOGRAMA PARA MARCADOS DE SEGURIDAD SE OBTIENE MEDIANTE UN HOLOGRAMA DE TRANSMISION LASERICA (1-4) FORMADO A MODO DE IMAGEN EN RELIEVE SUPERFICIAL Y UN REVESTIMIENTO DE UNA CAPA METALICA DELGADA (5) SOBRE LA IMAGEN EN RELIEVE SUPERFICIAL CON LO QUE EL HOLOGRAMA ES CAPAZ DE REFLEJAR LUZ DESDE UN LASER (10). LA CAPA METALICA TIENE, PREFERENTEMENTE, UN GROSOR DE 500 ANGSTROMS Y EL HOLOGRAMA SE PUEDE MONTAR SOBRE EL SUSTRATO (7) DE UN ARTICULO EN EL QUE SE QUIERE COLOCAR LA MARCA DE SEGURIDAD DEFINIDA POR EL HOLOGRAMA. EN UN ASPECTO DE LA INVENCION, HAY UN APARATO PAR LA LECTURA DE LA LUZ REFLEJADA DESDE EL HOLOGRAMA QUE COMPRENDE UN LASER (10) PARA PROYECTAR UN HAZ (9) SOBRE EL HOLOGRAMA A LEER Y UN DISPOSITIVO (31) Y UNOS DISPOSITIVO LOGICOS ASOCIADOS PARA EL RECONOCIMIENTO DE UNA IMAGEN REAL DEL HOLOGRAMA. EL APARATO PRESENTA LA VENTAJA DE QUE TANTO EL LASER (10) COMO EL DETECTOR (31) SE ENCUENTRAN COLOCADOS EN EL MISMO LADO DEL HOLOGRAMA A LEER.
