Light induced fluorescence LIDAR developed and employed at the National Aviation Academy of Azerbaijan

摘要

A new laser induced fluorescence (LIF) KA-14 LIDAR (Light Identification Detection and Ranging) system for detecting of oil spills on the sea surface was developed and employed at the National Aviation Academy of Azerbaijan. Laser's parameters used in LIDAR are as follows: ˙laser CFR 200- type QUANTEL, λ = 355 nm, beam ? = 5.35 mm, f = 20 Hz, pulse duration and power τ = 7 ns and 60 mJ, respectively. The first results of measurements in the laboratory and the results of measurements at natural environment from distances up to ~ 200 m revealed perspectives for using this LIDAR for detection of oil contaminations on sea as well as on earth surfaces (these measurements have been performed at Pirallahi Oil-Gas Production Company, Absheron peninsula, Baku, Azerbaijan). In the present work the results of emission spectra of crude oils taken from different regions of Absheron peninsula as well as the emission spectra of the oil spills on the surface of Caspian sea will be reported and discussed. These measurements open perspectives for using developed LIDAR for determination of place of oil-gas production company from which leakage takes place.
