Abstract
trata-se de um aparelho para detectar um parâmetro abaixo de uma superfície terrestre que inclui uma fibra óptica disposta abaixo de uma superfície terrestre e compreendendo pelo menos um sensor de rede de bragg de fibra configurado para detectar o parâmetro e uma fonte de luz de banda larga disposta abaixo da superfície terrestre e configurada para emitir luz numa banda larga de comprimentos de onda para iluminar a pelo menos uma rede de bragg de fibra. um interrogador óptico é disposto abaixo da superfície terrestre e configurado para receber luz refletida por pelo menos um sensor de rede de bragg de fibra e para transformar um desvio no comprimento de onda da luz refletida numa variação de intensidade de luz. um fotossensor é configurado para medir intensidade de luz recebida do interrogador óptico. componentes eletrônicos são acoplados ao fotossensor e configurados para medir uma voltagem representando a intensidade de luz no fotossensor para detectar o parâmetro.
