Abstract

método de detecção distribuída, método para processar dados provenientes de um sensor de fibra óptica distribuído , aparelho sensor de fibra óptica distribuído , aparelho processador , programa de computador , e, sensor de fibra óptica distribuído. é descrito um método de detecção óptica de fibra distribuída no qual uma fibra óptica (104) é interrogada com radiação eletromagnética; radiação retrodispersa é detectada; e os retornos são processados para fornecer um sinal de medição (310) para cada qual de uma pluralidade de porções de detecção longitudinais da fibra óptica. o método compreende analisar os sinais de medição de um primeiro subconjunto de pporções de detecção longitudinais para prover uma primeira zona (306a) com uma primeira função de detecção e analisar os sinais de medição de pelo menos um segundo subconjunto de porções de detecção longitudinais para prover pelo menos uma segunda zona (306b) com uma segunda função de detecção diferente . as diferentes funçõs de detecção podem incluir detectar diferentes eventos de interesse. em alguns modalidades , a geometria da fibra pode prover diferentes zonas de detecção (406a, 406b).
