Abstract

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.
