Karazin Kharkiv National University popup.description2  The research object – holographic laser system for ecological remote monitoring of atmosphere surface layer. The research objective – development of construction principles of holographic laser system intended for remote ecological monitoring of atmosphere surface layer. Research method – theoretical and experimental study of remote gas and aerosol compositions determining in the atmosphere surface layer by using laser radiation. Theoretical analysis of Differential Absorption (DA) and Spontaneous Raman Scattering (SRS) for remote analysis of the atmosphere surface layer was carried out. Structural block-diagram of DA and SRS lidars have been developed. The effectiveness of the developed SRS lidar was evaluated by using computer simulations. For the first time, the new holographic method of remote micro-objects by using limited coherence lasers has been theoretically substantiated and experimentally tested. This method can be successfully used in the lidar holography to remotely obtain information concerning atmospheric aerosols. The scheme of digital holographic polarizing microscope (DHPM) is developed. It was shown that Stokes parameters and distribution of aerosol microparticles with different physical properties can be determined by the DHPM. Two variants of structural schemes of fundamentally new holographic laser system (RHLS) for remote ecological atmosphere monitoring, in which the aerosol is studied by lidar holography, while the gas analysis channel was created using DP and SRS methods have been developed. The experimental tests of the some technical units for the DGLS were carried out by using the created laboratory models. The test has showed the possibility of practical application of the DGLS for laser monitoring of gases and aerosol composition of the atmosphere surface layer.
