Realization of a narrow band filter for methane gas detection

Natural gas leaks frequently during exploitation, transportation, storage and use. It can cause energy loss and even cause fire, explosion and other co nsequences, seriously threaten people's lives and property. Methane is the main component of natural gas, and its effective detection and identification is of great significance for timely detection of natural gas leak age accidents. Various approaches have been proposed to detect methane, however the detection and identification of methane leakage by infrared technology has become a hot topic in the world. A narrow band filter developed based on the infrared characteristic absorption peak of methane is one of the core optical componen…
