Abstract

A compact measuring - information multi-channel spectroellipsometric system for monitoring the quality of aquatic environment, that is based on the combined use of spectroellipsometry and training, classification, and identification algorithms is described. This system is differed from modern analogues by the use of a new and very promising method of ellipsometric measurements, an original element base of polarization optics and a complex mathematical approach to estimating the quality of a water object subjected to anthropogenic influence.The spectroellipsometric system can be used in different fields where the water quality should be estimated or the presence of a particular set of chemical elements should be revealed. The system solves these problems by real-time monitoring of the aquatic environment. In the stationary version it allows the tracking of the dynamics of water quality in a stream, and when placed on a ship, it allows the measurement of water parameters along the route.Some experimental data and calculations are given. Assessment of the system precision is realized for water reservoirs located in South Vietnam.

Highlights

Problem of the aquatic environment operative diagnostics is arisen practically in many human base including agriculture, medicine, industry and service. The development of these anthropogenic processes poses the problem of water pollution control and synthesizing monitoring system for water quality assessment in active regime
The creation of multi-channel polarization optical instrumentation and use of spectroellipsometric technology are very important for the real-time ecological control of aquatic environment
A technology of combined use of spectroellipsometry and algorithms of optical spectrums identification and recognition allows the creation of a standard integral complex of instrumental, algorithmic, modular and software tools for the collection and processing of data on the aquatic environment quality with forecasting and decision - making functions [2, 3]

Summary

Introduction

Problem of the aquatic environment operative diagnostics is arisen practically in many human base including agriculture, medicine, industry and service The development of these anthropogenic processes poses the problem of water pollution control and synthesizing monitoring system for water quality assessment in active regime. Specific attention was given for the water quality control in the estuary zones taking into consideration of pollution sources compounded in territories bordering the South China Sea. This paper describes new version of spectroellipsometric system that develops and realizes the functions of contaminant identification for multi-component solutions. In developed ellipsometry devices BMPS with no moving polarization elements combined with high sensitivity, stability and measurement speed. This approach to solving the problem in the foreign studies spectroellipsometry not known
