Ellipsometry is an optical technique that uses the change in the state of polarization of light upon reflection and refraction for the in-situ and real-time characterization of surfaces, interfaces, thin films in the physics, and liquid solutions in the hydrochemical investigations. Spectroellipsometry methods are used for the undestroying investigation of chemical and physical characteristics of solid materials and liquid solutions. These methods are based on the registration of optical polarization effects appearing under reflection or deformation of the light wave as a result of its interaction with studied object. In the solid physics, spectroellipsometry gives possibility to measure simultaneously amplitude and phase characteristics of studied object and allows the precise definition of the film thickness and optical constants for film material. The diagnostics of liquids gives possibility to assess the concentration of chemicals dissolved and weighed in the liquid as well as to determine the spots of pollutants on the water surface. In this paper the task of liquid solutions identification is considered basing on the measurement data of optical characteristics delivered by the multi-channel spectroellipsometer. Learning decision making system is proposed. Four algorithms are proposed and analyzed for this task solution. These algorithms are based on different procedures for the spectral image recognition. Comparative empirical assessments are given for precision of these algorithms and dependence of index for identification reliability on the solution concentration is shown. Efficiency of proposed algorithms is shown by means of the examples of diagnostics of water systems located in South Vietnam. ” The reported study was partially supported by RFBR, research project No. 13-07-00146”.
