Abstract

ENTIDADES SIMPLES TALES COMO FIBRAS (12) SON SUMINISTRADAS UNA CADA VEZ A UNA CORRIENTE DE FLUIDO, Y UNA BOQUILLA ORIENTA LAS ENTIDADES DE FORMA QUE CADA ENTIDAD A LO LARGO DE SU LONGITUD (DIMENSION MAYOR) ES GENERALMENTE PARALELA CON LA DIRECCION DEL FLUJO DEL FLUIDO. LA ENTIDAD PENETRA ENTONCES EN UNA ZONA DE PRUEBA (36) Y UN SENSOR MIDE LOS DATOS DE LA ENTIDAD TALES COMO LA VELOCIDAD DE LA ENTIDAD A MEDIDA QUE PASA A TRAVES DE LA ZONA DE PRUEBA. UNA CONFORMACION MAS ADECUADA INCLUYE UN HAZ COLIMADO DE LUZ (34) Y DOS FOTODETECTORES (46A, 46B) POSICIONADOS LADO CONTRA LADO PARA MEDIR LA EXTINCION LA LUZ PROVOCADA POR LAS FIBRAS QUE PASAN A TRAVES DE LA ZONA DE PRUEBA. OTRO SENSOR (52) PUEDE ESTAR DESTINADO A DETECTAR LA LUZ ESPARCIDA HACIA UN ANGULO DE ALREDEDOR DE 40 (GRADOS) . LAS SEÑALES DEL SENSOR SE USAN PARA GENERAR DATOS QUE SE CORRESPONDEN CON PARAMETROS TALES COMO LONGITUD, ANCHO DE LA FIBRA, FINEZA, AREA DE SU SECCION DE CORTE, MADUREZ, CIRCULARIDAD DE LA SECCION DE CORTE, FORMA,RUGOSIDAD DE LA SUPERFICIE, ETC. EL FILTRADO OPTICO SUMINISTRA INFORMACION ACERCA DE LA COMPOSICION (NATURAL O FABRICADA A MANO) Y APARIENCIA (COLOR Y POLARIZACION).
