Fig. 9.10 Spectral characteristics of ammonia solution in the water. Solution concentration is
shown on spectral curves
from measurements in the visible spectral region permits to synthesize an expert
system for an adaptive identi
cation of the environmental parameters (ESAIEP).
The system
s structure includes a compact multi-channel spectroellipsometer
(MSP), information interface with computer, computer software (STW), and
extending database (Mkrtchyan and Krapivin 2014).
The principle of the ESAIEP functioning is based on
'
fixation of changes of the
light
flux at the MSP output and their transformation into a digital code. Further
processing of these data with respect to their ef
fl
ciency is determined by the STW
composition containing various algorithms of recognition of 2D objects. The
adaptability of the recognition procedure is determined by the level of accumulated
knowledge about special features of intensity fluctuations and polarizing properties
of the light re
ected from the water surface. The STW includes the means that make
it possible, in case of uncertain identi
fl
cation of the pollution spot, to make an
expert decision based on the visual analysis of its spectral image. This procedure is
carried out in the mode of dialogue with ESAIEP, and if decision is made, the
operator can
fix it in the database in the form of a standard for subsequent situations
of an appearance of similar spots. Figure 9.11 characterizes general view of the
ESAIEP.
Spectral image of water solution in optical range is in
volumetric vector that
can be considered as element of cluster in the vector space describing concrete
concentration of chemical element
in water solution. Following to the signal
