| Abstract: | The sensor technology based on spectral absorption and Ring-down optical resonant cavity was integrated together,which was proposed as a design idea.The quantitative relationship between optical intensity and gas density combined with the theory of Ring-down optical resonant cavity to design absorption cavity of gas(CH4)sensor that was based on Ring-down cavity.The absorption cavity was designed to solve the problem that it is difficult for traditional gas sensor to improve the accuracy and sensitivity in d... |
