“…The peculiarity of the extracellular matrix structure of sound SD is a random distribution of directions ( ( ) y x × ρ ) of the protein crystals optical axes (figure 2). Extracellular matrix of oncologically changed object of investigation is characterized by a set of ordered "the newly formed" collagen fibrils with a greater value of the birefringence parameter [25][26][27][28][29][30][31][32]. …”

To characterize the degree of consistency of parameters of the optically uniaxial birefringent protein fibrils nets of biological tissues a new parameter -complex degree of mutual anisotropy is suggested. The technique of polarization measuring the coordinate distributions of the complex degree of mutual anisotropy of biological tissues is developed. It is shown that statistic approach to the analysis of complex degree of mutual anisotropy distributions of skin derma of various optical thicknesses appears to be more sensitive and efficient in differentiation of physiological state in comparison with investigations of complex degree of mutual polarization of the corresponding laser images.

“…Among the most spread traditional methods for studying the scattered light fields, one can separate the following independent directions: "scalar" (photometry and spectrophotometry) 3,4 and "vector" (polarization nephelometry, Mueller-matrix optics) . Using these approaches, determined are interrelations between the sets of statistical moments of the 1-st to 4-th orders 6,7,11,15,20,26,27,31 , correlation functions 13,18,19,22,27 , fractal dimensionalities 6,7,26 that characterize phase-inhomogeneous or rough surfaces and coordinate distributions for phases 15,16,19,28 , azimuths and ellipticity of polarization in their laser images . In parallel with traditional statistical investigations, formed in recent 10 to 15 years is the new optical approach to describe a structure of polarizationally inhomogeneous fields in the case of scattered coherent radiation.…”

Adduced in this work are the results of investigation aimed at analysis of coordinate distributions for azimuths and ellipticity of polarization (polarization maps) in laser images of three types of biological phase-inhomogeneous layers (PhIL) -bulk scattering layers. To characterize polarization maps for all the types of PhIL, the authors have offered to use three groups of parameters: statistical moments of the first to fourth orders, autocorrelation functions, logarithmic dependences for power spectra related to distributions of azimuths and ellipticity of polarization inherent to PhIL laser images. Ascertained are the criteria for diagnostics and classification of PhIL optical properties. The possibilities of the local wavelet-analysis of polarization-inhomogeneous laser image of myocardium tissue histological sections were considered. The criteria for the differentiation of the transformation of birefringence optical-anisotropic structures of blood plasma at different scales of their geometric dimensions were determined.

Mueller-matrix processing of biological tissues polarization images and reconstruction of parameters phase and amplitude anisotropy

et al. 2014

View full text Add to dashboard Cite

A new azimuthally stable polarimetric method for processing of microscopic images of optically anisotropic structures of different biological layers histological sections is proposed. A new model of phase anisotropy definition of biological tissues by using superposition of Mueller matrices of linear birefringence and optical activity is proposed. The matrix element 44 M has been chosen as the main information parameter, which value is independent of rotation angle of both sample and probing beam polarization plane.
