4.1 Intelligent system with virtual broadband polarized “electronic eye”
An intelligent mobile hardware and software microsensory system “ISPB” with a
broadband polarized “electronic eye” is developed by us to recognize information patterns,
e.g., of biomatters, soil, food products. The sensor intended for measuring the light
polarization consists of a send-emitting module and a virtual polarizer with a self-learning
software. If a polarized light penetrates, e.g., in a human biomatter (blood, saliva, sweat,
urine, tears), then the plane of polarization is turned through angle depending on the
concentration of individual components in a biological fluid. A refractive index of blood
components strongly depends on the polarizability of protein structures in particular. The
use of the virtual polarization also gives an opportunity to determine polluting and foreign
surface layers on an investigated matter, produce information patterns of objects, e.g., food
products for the personal and social biosafety (Fig. 26a) and for generating information
patterns of the human functional state. Fig. 26b,c,d,e shows obtained average reflection
factors of a scattered light and the polarized one for the investigated food products (soda,
salt, water, milk) with the rotation of the plane of polarization (0
°
, 30
°
, 60
°
, 90
°
) in a direction
to the plane of light incidence. If there are some surfaces with refractive indexes being
different from a refractive index of an investigated matter, then the part of light is thrown
back, but the rest of this one passes through the matter partially being reflected from it and
after that goes out again. The reflection coefficient differs from the reflection factor of the
investigated matter. Thus, the intelligent system “ISPB” makes it possible to determine
refraction and reflection indexes for any light angles and any degrees of its polarization but
also to carry out the research and the control of the quality of matters with impure
substances, surface foreign or polluting films. “ISPB” is especially very important for the
application in biotechnology, ecology, food industry, precision agriculture or for a personal
and social biosafety [1, 2, 8].
