Abstract

UN DISPOSITIVO (10) PARA LA INSPECCION DEL REVESTIMIENTO DE FIBRAS OPTICAS Y METODO PARA DETECTAR DEFECTOS EN TALES FIBRAS. EL DISPOSITIVO INCLUYE UN LASER PARA ILUMINAR EL REVESTIMIENTO DE LA FIBRA CON UN HAZ COLIMADO DE ENERGIA LUMINOSA (20 O 22), Y DETECTORES (46 Y 48) PARA DETECTAR CUALQUIER DISPERSION DEL HAZ (20 O 22) CONSECUENCIA DE UN DEFECTO EN EL REVESTIMIENTO DE LA FIBRA. LOS DETECTORES (46 Y 48) ESTAN MONTADOS PARA RECOGER LA DISPERSION PRODUCIDA FUERA DEL PLANO RADIAL DEFINIDO POR EL GIRO ANGULAR DEL HAZ (20 O 22) CON EL REVESTIMIENTO DE LA FIBRA. EL METODO COMPRENDE LAS ETAPAS DE ILUMINAR UNA FIBRA OPTICA CON UN HAZ COLIMADO DE ENERGIA Y DETECTAR CUALQUIER DISPERSION DEL CITADO HAZ.
