Abstract

avaliar um fluido, incluindo transmitir um feixe de luz através do fluido para um detector enquanto oscila um comprimento de caminho percorrido através do fluido pelo feixe de luz a uma primeira frequência de oscilação; medir uma intensidade dependente do tempo da luz incidente no detector responsiva a uma interação do feixe de luz com o fluido para produzir um sinal de intensidade dependente do tempo; filtrar o sinal de intensidade dependente do tempo para recuperar um sinal dependente de caminho que oscila na primeira frequência e indicativo de uma propriedade de absorbância do fluido; e estimar um parâmetro de interesse do fluido usando o sinal dependente do caminho. a intensidade dependente do tempo pode ser indicativa da absorbância verdadeira em múltiplos comprimentos de onda do fluido ou fluidos sobre a diferença máxima de comprimento do caminho, de modo a permitir a quantificação das porcentagens de cada um desses fluidos. a filtragem pode incluir filtrar a frequência sozinha ou o uso de um amplificador de bloqueio sensível à fase.
