Abstract

resumo patente de invenção: "medição de distância utilizando reflectometria óptica incoerente". a presente invenção refere-se a um método para estimar uma distância inclui: gerar um sinal óptico possuindo um comprimento de onda que está dentro de uma faixa de comprimentos de onda, o sinal óptico modulado através de um sinal de modulação possuindo uma frequência de modulação; transmitir o sinal óptico modulado a partir de uma fonte de luz na fibra óptica, a fibra óptica em contato com uma tensão móvel induzindo o elemento localizado na posição ao longo da fibra óptica, a fibra óptica incluindo uma pluralidade de localizações de sensoriamento configuradas para refletir luz dentro da faixa de comprimento de onda quando sobtensão a partir do elemento indutor de tensão e transmitir luz dentro da faixa de comprimento de onda quando não sobtensão a partir do elemento indutor de tensão; receber um sinal refletido incluindo luz refletida a partir de pelo menos uma das localizações de sensoriamento; demodular o sinal refletido com um sinal de referência para gerar dados de sinal refletidos; e determinar a distância até a posição ao longo da fibra óptica baseada nos dados de sinal refletidos.
