Abstract

Dispositovo de discriminación de fluidos con índices diferentes, que incluye un acoplador de fibra óptica (4) con tres extremos a los que se hallan conectados respectivamente una fuente luminosa (1) con semiconductor en la que se halla modulada la intensidad, un fotodetector (2) con semiconductor y una sonda óptica constituida por una fibra óptica (3) multimodo con el mismo perfil de índices que las fibras del acoplador, caracterizado porque el extremo (3a) de la fibra óptica tiene forma de punta obtenida por estirado en caliente.
