We developed a Raman lidar with ultraspectral resolution for automatic airborne monitoring of pipeline leaks and for oil and gas exploration. Test flights indicate that a sensitivity of 6 ppm for methane and 2 ppm for hydrogen sulfide has been reached for leakage detection.
The possibilities of the Raman method of radiocarbon measurements in the field of gas analysis are investigated. With
the help of veneer gas mixtures of carbon monoxide, carbon dioxide-12, carbon dioxide-13, methane, formaldehyde, the
micrometric characteristics of Raman lidars were found, which in most cases coincided with the claimed ones. When gas
mixtures are supplied, the diluent gas in which differs from air, the broadening of the spectral lines associated with the
interactions between the particles, the results, to significant errors in the measured concentration. These effects, which
negate the advantages of the measurement method, are investigated in the framework of this paper. The results of determining
the coefficients for correcting the readings of gas analyzers with the achievement of inaccuracies from various
diluent gases, as well as the data of the prototype Raman lidar.
