Methane is widely distributed in nature. Methane is the simplest organic matter and the main component of natural gas, biogas, pit gas, etc. It is commonly known as gas. Methane is also the hydrocarbon with the smallest carbon content (the largest hydrogen content). It can be used as fuel and raw material for the manufacture of hydrogen, carbon black, carbon monoxide, acetylene, hydrocyanic acid and formaldehyde. Methane is mainly used as a fuel, such as natural gas and coal gas, and is widely used in civil and industrial applications. As a chemical raw material, methane can be used to produce acetylene, hydrogen, synthetic ammonia, carbon black, nitrochloromethane, carbon disulfide, monochloromethane, dichloromethane, chloroform, carbon tetrachloride and hydrocyanic acid, etc.

In industrial occasions, once methane leaks from the pipeline, if it is mixed with air and encounters open flames and electric sparks, it will be easily ignited and cause a fire, causing immeasurable losses. Therefore, methane detection is required. At present, a commonly used methane detector uses the absorption characteristics of methane gas to a certain wavelength of laser light. When the laser beam is directed to the detection target, such as a gas pipeline, the scattered laser light will be reflected back from the target object, and the detector will receive the reflected back light. laser and measure its absorptivity to determine whether leakage occurs.
