Abstract

METODO Y APARATO PARA CONTROLAR LA REFLECTIVIDAD DIFUSA DE UNA PARTE DE UNA SUPERFICIE, SIENDO EL METODO ESPECIALMENTE APLICABLE A LA DETECCION DE BILLETES DE BANCO EN EL SUELO. LA SUPERFICIE (3) SE EXPONE A UN RAYO PROCEDENTE DE UNA FUENTE (2) DE RADIACION. AL MENOS PARTE DE LA RADIACION DIFUSA REFLEJADA POR LA SUPERFICIE (3) ES DETECTADA POR UN SENSOR (6) SITUADO DETRAS DE UNA ABERTURA (7), DE FORMA QUE ESTA DEFINE UNA POSICION DE DETECCION SITUADA DE TAL FORMA QUE LA INTENSIDAD DE LA RADIACION DIFUSAMENTE REFLEJADA QUE SE HA DETECTADO, NO VARIA ESENCIALMENTE DENTRO DE UN RANGO DE DISTANCIAS (D) ENTRE LA ABERTURA (7) Y LA SUPERFICIE (3). EL VALOR QUE REPRESENTA LA REFLECTIVIDAD DIFUSA DE LA SUPERFICIE (3) SE DETERMINA ENTONCES A PARTIR DE LAS INTENSIDADES DETECTADAS.
