Abstract

UN METODO DE MEDICION DE LA LONGITUD PRECISO EN EL CUAL UN GENERADOR DE SEÑALES (18, 20) DISTRIBUYE UN PULSO EN UNA LINEA DE TRANSMISION ELECTROMAGNETICA (24) A LO LARGO DE LA CUAL SE MUEVE, UN BLANCO ADAPTADO PARA PRODUCIR UNA REFLEXION PARCIAL DE LA SEÑAL EN LA POSICION A LO LARGO DE LA LINEA EN LA CUAL ES LOCALIZADO. UN DISPOSITIBO BIESTABLE (10) DETECTA LA SEÑAL REFLEJADA Y UN MEDIO PROCESADOR (12, 14, 16) PROPORCIONA UNA SALIDA REPRESENTATIVA DE FORMA PRECISA DE LA LONGITUD DE LA LINEA DE TRANSMISION ( U POR TANTO DE UN ARTICULO UN OBJETO A LO LARGO DEL CUAL LA LINEA ESTA DETERMINADA) ENTRE EL FINAL DE LA ENTRADA Y EL BLANCO.
