%X To characterize the degree of consistency of parameters of the optically uniaxial birefringent liquid crystals (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 biological tissues of various morphological and physiological states and 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. 1. Introduction In [1, 2] for characterizing the consistency between the polarization states the laser object field in the points with the intensities , a new parameter-complex degree of mutual polarization (CDMP) in the next form This Ħ°two-pointĦħ theoretical approach was extended to the analysis of polarization-inhomogeneous laser images of human BT with the aim of experimental diagnostics of optical anisotropic structure [3]. In [4] a method of direct polarization measurement of the real part of CDMP for different points ( ) of optically thin image (attenuation coefficient ) of BT layers is proposed where and are the phase shifts between the orthogonal components , of laser amplitude in object field. The ranges of changes of the 1st¨C4th distribution order statistic moments of the corresponding laser images, important for diagnostics of the human connective tissue oncologic state were determined in [5, 6]. On the other hand, such analysis techniques of lead to disregarding the BT extracellular matrix birefringence, which is a principal physical mechanism of their polarization-heterogeneous images formation [7¨C11]. That is why it appears to be important to search for new diagnostic parameters directly characterizing the degree of consistency of optical axes and birefringence orientations of various points of protein fibrils network forming the BT extracellular matrix [3]. This paper is aimed on investigation of diagnostic possibilities of optical-anisotropic structure of biological tissues extracellular matrix of different morphology and physiological state by means of statistic analysis of a new parameter-CDMA coordinate distribution. 2.
