DEVELOPMENT OF FLUORESSENT-COLORIMETRIC COMPLEX FOR MEASURING OF DEPTH OF OIL FILM ON THE SURFACE OF SEA WITH INTERSENSOR CALIBRATION
(pp. 54-59)

Abstract. The paper is devoted to development scientific-methodical basics of construction of fluorescent-colorimetric measurements of depth of oil film on the sea surface using the intersensor calibration principle. The peculiarity of suggested complex is thatin orderto carry out the operations of periodical calibration of fluorescent subsystem the two-level calibration system is used. Advantages and shortages of fluorescent and colorimetric methods of measuring of oil film depth on the sea surface are analyzed. The necessity of utilization of intersensor calibration principle in the complex of fluorescent-colorimetric measurements of oil film depth is stressed out. The techniques of construction and an algorithm realization of intersensor calibration in the complex for measuring of oil films depth is described. The matter of suggested techniques is that the initial assessment of oil film depth by help of colorimetric measuring instrument with relatively higher error should be carried out. Then depending on received initial estimate the accurate measurement is to be carried out by measuring instrument functioning on the basis of analysis of reflection spectrum. The necessity of adaptive change of transmission band width of of filter of receiving part depending on colorimetric measuring of oil film depth is grounded. The method for removal of effect of atmospheric aerosol on value of obtained result is suggested. It is shown that utilization of known formula of Angstrom upon three wavelengths measurements make it possible to develop a methodic to remove effect of aerosol on result of measurements.

Keywords: oil film, complex of measurements, colorimeter, fluorescent measuring instrument, aerosol.
