| Abstract: | This article carried theoretical analysis on the minimum laser power which is indispensable to the scheme of remote detection methane gas by using a single laser source. By experiment, we attained the variational trend between received light power and measurement precision and concluded that if concentration of methane gas is 150ppm, we can respectively accomplish measurement, effective measurement and accurate measurement when received light power is above 3nW, 10nW and 50nW. |
