Abstract

ESQUEMA RECURSIVO DE TELEMETRIA POR FIBRA óTICA MULTIPLEXADO EM DIVISãO DE FREQüêNCIA E/OU DIVISãO DE COMPRIMENTO DE ONDA PARA UM SISTEMA SENSOR óTICO. A presente invenção refere-se a um sistema sensor de fibra ótica é descrito, o qual inclui uma primeira fibra sensora e uma primeira fibra de referência, acoplada em uma sua extremidade ao lado de um primeiro acoplamento ótico. Um primeiro refletor seletivo de comprimento de onda é acoplado á outra extremidade de cada uma das primeira fibra sensora e de acordo com a primeira fibra de referência. Uma segunda fibra sensora é acoplada em uma extremidade a um lado de um segundo acoplamento ótico. O outro lado do segundo acoplamento ótico é acoplado a um lado oposto de um dfos primeiros refletores seletivos de comprimento de onda acoplado em um lado á primeira fibra sensora e á primeira fibra de referência. O sistema também inclui um segundo refletor seletivo de comprimento de onda acoplado á outra extremidade de cada uma de acordo com a segunda fibra sensora e de acordo com a segunda fibra de referência. Os segundos refletores seletivos de comprimento de onda são operacionais em um comprimento de onda diferente de um comprimento de onda operacional dos primeiros refletores seletivos de comprimento de onda.
