Abstract

REFLECTOMETRO OPTICO DE DOMINIO TEMPORAL UN REFLECTOMETRO OPTICO DE DOMINIO TEMPORAL QUE INCORPORA UN EXPANSOR DE IMPULSOS (16) COLOCADO PARA DISPERSAR LA FRECUENCIA DE LOS IMPULSOS DE CORTA DURACION (14) DESDE UN GENERADOR DE IMPULSOS (12). EL EXPANSOR DE IMPULSOS (16) ES UN FILTRO DE ONDAS ACUSTICAS DE SUPERFICIE (SWA). LOS IMPULSOS CON UNA FRECUENCIA DISPERSA (18) SON DE LARGA DURACION Y, CUANDO SE AMPLIFICAN, SE UTILIZAN PARA MODULAR LA SALIDA OPTICA DE UN DIODO LASER (24). LA SALIDA OPTICA SE ALIMENTA EN UNA FIBRA OPTICA (32) PARA LLEVAR A CABO LAS MEDIDAS REFLECTOMETRICAS DE DOMINIO TEMPORAL CONVENCIONALES. UN SEGUNDO FILTRO SWA COLOCADO A MODO DE COMPRESOR DE IMPULSOS TRANSFORMA LAS SEÑALES DETECTADAS EN IMPULSOS CORTOS (52).
