Determination of praline concentration in samples of natural waters, based on the measurement value angle of the plane of polarization of radiation of a certain wavelength λ, which has been studied by the liquid thickness l = 5 sm was developed. Three wavelength λ = 400, 450, 500 nm were used. A series of reference samples was produced: aqueous solutions of L and D forms proline of a known concentration within c = (0.001 – 0,1) %. Based on these studies, for each λ gauge dependent quantities of angle α = f (c) was built. Using them and conducting measurements of angles α for the real natural environments, the possibility of determination of the concentration of proline in them was actualized. It was determined that in waters within the city of Chernivtsy and its surroundings occured proline of two forms: L and D, the concentration of which is within c = (0,005 - 0,094)%
A theoretical basis for the method of polarization-interference mapping of optically thin polycrystalline films of human biological fluids is given. The coordinate distributions of the value of the local contrast of the interference distributions of the polarization-inhomogeneous microscopic images of polycrystalline films of the synovial fluid of the human joint are investigated. In the framework of the statistical (statistical moments of the 1st-4th order) approaches, objective criteria for the distribution of the values of local contrast are established. The possibility of differentiation of weak changes in the optical anisotropy of blood films of healthy and patients with breast cancer patients is determined.
The principles of the use of fractal analysis in the problems of polarization mapping of microscopic images of biological preparations are considered. Myocardial tissue of the deceased with various pathological and necrotic changes was selected as the object of study. A model of the polycrystalline structure of such an object is proposed. Obtained maps of the ellipticity of the polarization of microscopic images of such an object. Within the framework of fractal analysis, the statistical moments of the 1st - 4th orders were found, which characterize the distribution of the logarithmic dependences of the power spectra of polarization ellipticity maps. The criteria for differentiation of various pathological states of myocardial tissue are determined.
This report contains the results of approbations of the polarization correlometry method (PCM) – statistical mapping of biological tissues fractal structure (myocardium and brain - “fibrillar optically anisotropic networks” and the wall of the rectum - “island optically anisotropic structures”) and liquids (polycrystalline films of synovial fluid - a superposition of “structured and island networks of biological crystals").
The results of the multifunctional Stokes polarimetric mapping of the manifestations of phase and amplitude anisotropy of histological sections of the internal organs of rats are presented. The methods of statistical analysis of vector-parametric images are used. Criteria for the differentiation of pathological conditions are obtained.
Perfect homo- and heteroepitaxial structures of n- and p-type conductivity on CdSb, In4Se3, In4Te3 semiconductors and their solid solutions were grown. On formed p-n-junctions there were investigated spectral dependence of photo-emf and detectivity in λ = 1 - 3 μm interval. It is shown the possibility of their using as IR-photodetectors.
