Board Lidar based on the diode lasers for ecological monitoring

摘要

Detection and identification of organic gases and the most toxic chemical agents in the atmosphere by diode lidars in the band of the overtones and combined tones of the C-H vibration are proposed. This approach based on the spectroscopic data of the main toxic substances, which were measured in our laboratory and also on the field experiment using diode lidar. Our experience involved both compact 1 microJoule pulsed diode backscattering lidar (905 nm) with single photon detector and 3 mW continuous wave (CW) differential absorption (1500 - 1650 nm) lidar (DIAL). An example of the clouds and aerosol plume (located at 6 km far from lidar) monitoring by backscattering lidar are presented.
