Abstract

An implementation of laser absorption wavelength-modulation spectroscopy technique combined with quadrature detection of scattered radiation for remote monitoring of atmospheric industrial pollution by means of a compact lidar gas sensor, that may be installed at unmanned aerial vehicles, is presented. The instrument may be used for gas pipeline leak search and monitoring toxic gases near landfills, waste incinerators and other hazardous industries, analyze the internal atmosphere at industrial buildings and technological cycles control, providing sensitivity level of tens ppm*m at typical distances of tens meters. In order to increase the sensitivity of the device, in addition to temperature stabilization the laser radiation frequency is stabilized using a reference spectral absorption line of the selected gas.
