An adaptive spectroellipsometric technology for the precise real-time measurements of the quality of natural and waste waters

Spectroellipsometry is a peak of polarization optics. The creation of multichannel polarization optical instrumentation and use of spectroellipsometric technology are very important for the real-time ecological control of aquatic environment. Spectroellipsometric devices give us high precision of measurements. Spectroellipsometric multichannel measurements in an aquatic environment provide an information basis for the application of modern algorithms for the recognition and identification of pollutants. New original elements (coaxial polarization switchers and achromatic compensators), developed in IRE RAS, allow to design cheap polarization systems (for example, spectroscopic ellipsometers, polarization spectrometers, polarimeters, dichrometers, polarization microscopes and interferometers, sensitive photometers, differential reflectometers) without expensive standard polarization elements. Principal possibility exists of use of optical and infrared bands with wavelength up to 20 Me for studies of properties of superthin coatings, films and different structures at it's base.
