Abstract
APARATO PARA DETERMINAR EL PERFIL DE INDICE DE REFRACCION DE FIBRAS OPTICAS.UNA FUENTE LUMINOSA (1) ENVIA HACIA LA FIBRA UN HAZ DE LUZ QUE, DESPUES DE LA REFRACCION POR DICHA FIBRA, ES RECOGIDO POR UN ELEMENTO FOTOSENSIBLE (3) QUE PROPORCIONA INFORMES DE LUMINOSIDAD A UN APARATO DE RECOGIDA DE LOS DATOS (6) QUE OBTIENE A SU VEZ EL PERFIL DE INDICE DE REFRACCION A PARTIR DE ESTOS INFORMES. ENTRE LA FIBRA Y LA FUENTE LUMINOSA HAY UNA PANTALLA OPACA PERPENDICULAR A LA DIRECCION DE PROPAGACION DEL HAZ DE LUZ CON UNA HENDIDURA OBLICUA QUE INDIVIDUALIZA LA SECCION PLANA DELA FIBRA.
