Este estudo tem como objetivo realizar um sensor de gás in-situ baseado no princípio da espectroscopia de ondas milimétricas/submilimétricas. O sensor de gás in-situ será atraente devido à seletividade do gás, à medição paramétrica múltipla, como temperatura, pressão e densidade do gás, e à capacidade de medição in-situ. Um dos principais problemas técnicos a serem resolvidos é desenvolver um instrumento preciso o suficiente para discernir a mudança do espectro devido à variação de parâmetros como a temperatura. Neste artigo é investigado um sistema de medição de absorção de gás proposto, que consiste esquematicamente em uma célula de gás do tipo Fabry-Perot para comprimento de caminho longo efetivo e processamento de sinal vetorial para rejeitar o sinal de vazamento acoplado entre as portas de entrada e saída do ressonador, de modo a obter uma medição de absorção precisa. . Também está incluído um estudo paramétrico das características de absorção de oxigênio, que serve como valor previsto na avaliação do instrumento. O experimento nas bandas de 60 GHz e 120 GHz utilizando oxigênio demonstra a eficácia da configuração atual do sistema.

Abstract: This study is intended to realize an in-situ gas sensor based upon the principle of millimeter/submillimeter wave spectroscopy. In-situ gas sensor will be attractive because of gas selectivity, multiple parametric measurement such as gas temperature, pressure and density, and of the in-situ measurement capability. One of the major technical problem to be solved is to develop an instrument accurate enough to discern the spectrum change due to the variation of parameters such as temperature. In this paper a proposed gas absorption measurement system is investigated, which schematically consists of Fabry-Perot type gas cell for effective long path length, and vector signal processing to reject leak signal coupled between resonator input and output ports so as to achieve precise absorption measurement. Also included is an parametric study of oxygen absorption characteristics, which is served as the predicted value in the evaluation of the instrument. The experiment at 60 GHz and 120 GHz bands using oxygen demonstrates the effectiveness of the current system configuration.
