| Abstract: | CH4 is a kind of danger gas, how to detect it accurately and instantly is a very important project. This paper focuses on two different theoretical types of methane detection techniques which are fibre-optic absorption and light interference. It also illustrates the comparison between difference detection technique and frequency harmonic detection technique relate to fibre-optic absorption. At the same time, the detection precision of measures discussed in this paper are analysed. |
