The article is focused on the development of an automated laser measuring complex for dis-tance control of oil and petroleum product film thickness on the water surface (e.g., on a rough sea surface). The method of measuring the thickness of oil and petroleum product films on the water surface is described. A new multispectral laser method is based on the use of a discretely tunable laser source. The composition and structure of an automated laser measuring complex are described.
A new type of compact wastewater treatment plant has been developed to provide treatment (without chlorine) up to the level permitted for discharge into municipal wastewater treatment facilities or fishery water bodies. The technological scheme of one of the options of the purification station is described.
The problem of remote measurement of the thickness of oil films on water surface is considered and the method of remote control of oil pollution, based on the use of wavelength-tunable laser, measurement of the intensity of the reflected signal from the wavelength and application of a special algorithm for processing the results of laser measurements, is developed. It is shown that the developed method of remote control and algorithms of processing the received signals for the laser meter allow to establish the thickness of films of oil products on water surface (including the agitated sea surface) with an acceptable accuracy.
The physical basics of creating a lidar-radar complex for detecting gas pollutants in the atmosphere and controlling the state of the atmosphere are considered. To increase the reliability of remote measurements, a complex use of equipment operating in different spectral ranges is proposed. The combination of lidar and radar systems will make it possible to reliably determine concentrations of multicomponent atmospheric pollutants (using a lidar subsystem of differential absorption) and evaluate the speed and direction of their transfer (using a radar subsystem of meter range) and thereby obtain comprehensive information characterizing the operational environmental situation in the monitored area.
The paper describes a method of remote control of oil film thickness on rough sea surface using a laser with tunable wavelength. It is shown that the use of an algorithm for smoothing measurement data allows to accurately restore the thickness of oil films on the sea surface.
This paper considers a laser method of controlling oil contamination on the sea surface based on probing the sea surface with two optical beams - vertically downward and at an angle along the line of travel. It is shown that the use of the two-beam sensing method allows to detect oil contamination on the sea surface with high reliability and to distinguish it from areas with smooth irregularities of the sea surface and areas with high reflection coefficient.
This paper describes the selection of analytical wavelengths for a laser gas analyzer designed to monitor atmospheric pollution. It is shown that the developed method qualitatively takes into account all the main factors affecting the operation of the gas analyzer and is preferable in terms of efficiency.
