抄録

Differential absorption lidar (DIAL) is very useful for remote sensing of atmospheric molecules. Methane (CH4) is one of the greenhouse gases and for the DIAL experiments, the absorption around 3.39 μm is usually used. Continuous monitoring of the flamable CH4 gas leakage is very important especially in a factory or along a gas pipe line. In the case of such a high concentration monitoring, absorption around 1.67 pm can be used. In this paper, we developed a DIAL system to detect CH4 at a wavelength of 1.67 μm Infrared (IR) laser source at 1.67 μm is easily obtainable and fast photodetectors, such as InGaAs PIN photodiodes are available in this range.
