Abstract

EN UN APARATO PARA AUTENTIFICAR DOCUMENTOS (12) COMO BILLETES, LA LUZ REFLEJADA, O TRANSMITIDA, DE UN DOCUMENTO (12), SE FORMA MEDIANTE UN SISTEMA DE LENTES (20) A UN HAZ DE LUZ (32) QUE ES DIRIGIDO A UNA SERIE DE DIVISORES DE HACES SELECTIVOS DE LONGITUD DE ONDA (34) CADA UNO DE LOS CUALES TRANSMITE LUZ SUPERIOR A UNA LONGITUD DE ONDA CARACTERISTICA Y REFLEJA LUZ DE LONGITUD DE ONDA INFERIOR. LAS LONGITUDES DE ONDA CARACTERISTICAS DE LOS DIVISORES DE HACES (34) AUMENTAN O DISMINUYEN A LO LARGO DE LA SERIE. LOS HACES DE SALIDA RESULTANTES (36) SON PERCIBIDOS POR FOTOSENSORES (40) PARA PRODUCIR SEÑALES ELECTRICAS QUE SON DIGITALIZADAS. LOS DATOS RESULTANTES SE ANALIZAN, POR EJEMPLO, MEDIANTE LA COMPARACION CON DATOS CORRESPONDIENTES DERIVADOS DE UN DOCUMENTO GENUINO, PARA PROPORCIONAR UNA SEÑAL DE SALIDA EN UNA LINEA (48) INDICATIVA DE LA AUTENTICIDAD DEL DOCUMENTO (12).IN A DEVICE TO AUTHENTICATE DOCUMENTS (12) AS TICKETS, THE LIGHT REFLECTED, OR TRANSMITTED, FROM A DOCUMENT (12), IS FORMED BY A SYSTEM OF LENSES (20) TO A BEAM OF LIGHT (32) THAT IS DIRECTED TO A SERIES OF SELECTIVE WAVE LENGTH BEAM DIVIDERS (34) EACH ONE OF WHICH TRANSMITS SUPERIOR LIGHT TO A CHARACTERISTIC WAVE LENGTH AND REFLECTS LOWER WAVE LENGTH LIGHT. CHARACTERISTIC WAVE LENGTHS OF BEAM DIVIDERS (34) INCREASE OR DECREASE THROUGHOUT THE SERIES. THE RESULTING OUTPUT BEAMS (36) ARE PERCEIVED BY PHOTOSENSORS (40) TO PRODUCE ELECTRICAL SIGNALS THAT ARE DIGITIZED. THE RESULTING DATA IS ANALYZED, FOR EXAMPLE, THROUGH THE COMPARISON WITH CORRESPONDING DATA DERIVED FROM A GENUINE DOCUMENT, TO PROVIDE AN OUTPUT SIGNAL IN A LINE (48) INDICATIVE OF THE DOCUMENT'S AUTHENTICITY (12).
