313-315

Specific features of the formation of local and statistical polarization structures of laser radiation scattered in phase-inhomogeneous layers (PIL) of biological tissue (BT) were studied. The distribution of azimuth and eccentricity of boundary field polarization was found to correlate with the orientation-phase structure of multifractal PIL. A method of polarization phase reconstruction of BT architectonics was suggested.

This paper is devoted to the analysis and experimental testing of the concept of laser polarization biotissue probing. The methods of increasing the signal-to-noise ratio in coherent images of the optically anisotropic architectonics of the morphological biotissue structure are considered. The possibilities of polarization selection and contrasting of such images screened by other biotissues are examined. The influence of the depolarization degree of the scattered background on the signal -to-noise ratio is investigated. The possibilities of polarization correction of the probing beam for contrasting biotissue images are analyzed.

The interrelation of orientalion, anisotropy structure of biotissue architectonics and topological element distribution of John Matrices is investigated here. It is researched the analytical correlation of bioobject John Matrices microstructure with matrix element indices measured in the far field of Fraunhofer diffraction. The investigation is also dealt with the computer modelling and experimental researching the structure of matrix operator of multifractal amorphous - crystalline organization of different morphological structure biotissues.

W artykule badano współzależność pomiędzy orientacją, strukturą anizotropii architektoniki biotkanki oraz topologicznym rozkładem elementów macierzy Johna. Prowadzano badania nad analityczną korelacją pomiędzy mikrostrukturą bioobiektowej macierzy Johna a wskażnikami elementu macierzy zmierzonymi w części pola dyfrakcji Fraunhofera, znajdującej się w dużej odległości od żródła promieniowania. Prace badawcze dotyczą także modelowania komputerowego oraz badań eksperymentalnych struktury operatorów macierzy wielofraktalnej bezpostaciowo-krystalicznej organizacji różnych biotkanek struktur morfologicznych.

An automatic polarimetric system constructed at the Optical Engineering Division of the Warsaw University of Technology (Poland) and the evaluation method developed at the Department of Correlation Optics of Chernivtsi State University (Ukraine) are presented. The polarimeter has been designed and constructed to test the biotissues in the form of biopsy samples. After the system autocalibration the isocline and isochrome images are registered automatically. Correlation characteristics of the images calculated by the computer program provide the basis for formulating the medical diagnosis.
