Paper Abstract

A portable sensor based on tunable diode laser for remote sensing of methane (CH4) leakage at a wavelength of 1.65 μm was developed. Wavelength modulated spectroscopy technology is also applied. It was found that the sensor can detect a 10 cm3 min-1 city-gas leak with a sensor output equivalent to the range-integrated concentration over 100 ppm-mn.
