Abstract

"MéTODO PARA MEDIçãO DE PELO MENOS UM PARâMETRO SELECIONADO EM UMA LOCALIZAçãO DENTRO DE UMA REGIãO DE INTERESSE, MéTODO E APARELHO DE MEDIçãO DE UM PARâMETRO FìSICO SELECIONADO, APARELHO PARA MEDIçãO DE UM PARâMETRO FìSICO SELECIONADO EM UMA LOCALIZAçãO DENTRO DE UMA REGIãO DE INTERESSE, E MéTODO PARA MEDIçãO DE UM PARâMETRO EM UM DISPOSITIVO INTERFEROMéTRICO DE FIBRA óTICA". Trata-se de um método para medição de um parâmetro físico selecionado em uma localização dentro de uma região de interesse que compreende as etapas de: inserção de pulsos áticos em uma pluralidade de comprimentos de onda de interrogação previamente selecionados para o interior de uma fibra ótica (1) instalada ao longo da região de interesse, com refletores (2~ 0~, 2~ 1~, 2~ n~) dispostos ao longo da fibra ótica (1) formando um conjunto (9) de elementos sensores, em que a extensão de percurso ótico entre os referidos refletores (2) é dependente do parâmetro selecionado; detecção do sinal de interferência ótica de retorno em cada um dos comprimentos de onda selecionados; e determinação, com base no sinal de interferência ótica, da extensão de percurso ótico absoluta (L) entre dois refletores (2) na referida localização, e determinação, com base na extensão (L) de percurso ótico assim determinada, do valor do parâmetro selecionado na referida localização; em que a etapa de determinação da extensão de percurso ótico absoluta (L) compreende a realização de um processo no qual é estimada a diferença de fase entre os sinais de interferência de um par dos comprimentos de onda previamente selecionados, mediante utilização de um valor estimado para a extensão (L) de percurso ótico, sendo utilizada a diferença de fase estimada para realização de uma estimativa da fase em cada um desses comprimentos de onda, e em que a fase assim obtida é utilizada para realização de uma revisão do valor estimado da extensão (L) de percurso ótico, com o processo sendo repetido para alguns ou todos os pares de comprimentos de onda remanescentes em seq³ência, com base na extensão (L) de percurso ótico estimado para o par imediatamente precedente na seq³ência, sendo dessa forma realizada uma revisão progressiva da extensão (L) de percurso ótico até a mesma ser conhecida com um nível desejado de precisão.
