Ecological Systems and Devices Annotation << Back METHODS FOR THE SOLUTION OF SPECTROELLIPSOMETRY INVERSE TASKS V.F. Krapivin, F.A. Mkrtchyan Results of the investigations are stated in connection with the assessment of capabilities to use the sensors of optical and microwave ranges for the diagnostics of hydrophysical and hydrochemical systems having various spatial scales. Structure of information-modeling system for hydrochemical investigations (IMSHI) is synthesized. IMSHI consists the sensors of optical and microwave ranges and it realizes functions for the diagnostics and adaptive identifi cation of the liquids. The system is based on the base formation of spectral standards for the liquid solutions delivered by means of multi-channel spectrophotometer or spectroellipsometer and used for adaptive recognition of spectral images. Education process and following recognition are realized in accordance with the certain series of the methods, algorithms and procedures for accumulation, analysis, sorting and observation data processing. Assembly of all tools forms the information-modeling system oriented on the operative diagnostics of the state of the water objects when multi-channel information is delivered by the on-site and remote sensors and high-performance information technologies are used for the solution of the tasks related to the classifi cation and identifi cation of the water objects. A solution of operative multi-pronged task of the water quality control and state of hydrochemical systems when their spatial heterogeneity is taken into consideration and series of physical, chemical and biological factors exist to be as infl uencing on them is realized by means of the collection of computer algorithms and models that are the hydrochemical monitoring system. This collection gives a possibility to parameterize typical water balance on restricted territory that refl ects an interaction between hydrological cycle components. Under this, the system has adaptation function to the real hydrophysical object or process. The IMSHI can used under the water media or other liquids quality control under the expedition conditions when chemical laboratory no exist.
