Abstract
La invención se refiere a un método y a un sistema correspondiente, capaces de comprobar si los marcadores químicos de SERS o SERRS auténticos, que tienen una característica de dispersión de mejora de superficie característica única, están presentes o no en una marca legible por máquina aplicada en un documento de valor mediante el uso de un espectrómetro Raman adaptado para realizar un análisis de espectroscopía Raman de la marca. El método de acuerdo con la invención permite una detección rápida y fiable de la presencia de los marcadores químicos de SERS/SERRS, y es particularmente adecuado para comprobar la autenticidad de los documentos de valor, por ejemplo, tales como billetes de banco, moviéndose con respecto al espectrómetro Raman con una velocidad dada, y posiblemente con una velocidad alta, o exponiéndose brevemente al espectrómetro Raman.
