Abstract
In inelastic Raman scattering the scattered signal consists of radiation that has undergone a frequency shift which is characteristic for the stationary energy states of an irradiated molecule. Nowadays, Raman and fluorescence spectroscopy is commonly used in chemistry. Information on the radiation that results from transition between the vibrational energy states of the excited molecules, respectively, is specific to the chemical bonds and symmetry of molecules. This radiation therefore provides unique information regarding the irradiated molecule according to which the molecular species can be identified. Raman spectroscopy represents a particularly powerful tool for laser remote sensing because it allows us to both identify and quantify the trace constituent relative to the major constituents of a mixture. In this paper we present a multi-channel spectrometric lidar system which allows us to measure Raman and fluorescence spectrums that give us information on chemical signatures characteristic for chemical components of aerosol particles and pollutions. In the following, we describe the methodology, the system and we show experimental results.
