Methods: Biological samples. Three representative groups of polycrystalline blood plasma films were formed: 1 group consisted of blood plasma samples of polycrystalline adenoma; Group 2 consisted ofpolycrystalline adenocarcinoma, blood plasma samples are moderately differentiated (3+3 on the Gleason scale); Group 3 consisted ofpolycrystalline adenocarcinoma, blood plasma samples are poorly differentiated (4+4 on the Gleason scale). Results: The results obtained can be associated with changes in the ratio between the concentrations of albumin and globulin proteins in the blood plasma from patients with prostate tumors.

Such heterogeneity is characterized by the spatial distributions of the overall optical parameters (refractive indices and absorption) and their anisotropic components (linear and circular birefringence, linear and circular dichroism). In addition, there can be spatial and/or angular heterogeneity of the orientation, size, shape, and volume of the particles or domains constituting the overall physical body at the micro-and macrolevels [1-6]. A common feature of such optically heterogeneous objects is scattering of incident light. This scattering is the subject of optics of scattering media. Light interacting with biological objects is therefore scattered by biological structures. These can include various biological fluids (blood, lymph, cerebrospinal fluid, urine, bile, etc.) and tissues (muscle, connective, epithelial, nervous). All these biological objects typically exhibit multiple scattering and form optically turbid layers [7, 8]. The optical properties of such objects within the photometric approximation are described by the model of multiple scattering of scalar waves in a randomly inhomogeneous medium with absorption [1, 5-9]. If the optical thickness of a biological layer is insignificant (weakly or singly scattering media), then its properties with respect to light intensity conversion are traditionally determined with a model of single scattering within an ordered medium with densely packed scattering centers [10]. From the point of view of the geometric construction of such optically inhomogeneous layers, one can distinguish surface or rough scattering [10-12], as well as volume scattering [13-15]. Historically, there are three main approaches to the studies of the optical properties of such biological objects-1) spectrophotometric, that is based on the analysis of spatial or temporal changes in the intensity of scattered radiation in the optical range of electromagnetic wavelengths [16-19]; 2) polarimetric, based on the analysis of the distributions of the azimuth and polarization elliptic distributions, or the degree

A statistical analysis of the distribution of the number of characteristic values of the Stokes vector of polarizing microscopic images of histological sections of the internal organs of laboratory rats was carried out. The relationships between the values of statistical moments of the 1st - 2nd orders of magnitude characterizing the distribution of the number of characteristic values of the Stokes vector of polarizing microscopic images of histological sections of the internal organs of laboratory rats and the severity of the septic process are determined. Quantitative parameters that are most sensitive to septic conditions have been established, which ensure the implementation of statistically confidance differentiation of histological sections of the internal orga...

A relevant task is to generalize traditional techniques by incorporating new correlation-based "two-point" algorithms for the analysis of polarization images. Theoretical foundations of the mutual and autocorrelation processing of phase maps of polarization-structural images of samples of dehydrated serum films are given. The maps of a new polarization-correlation parameters, namely complex degree of coherence (CDC) and complex degree of mutual polarization (CDMP) of soft matter layer boundary field by the example of dehydrated serum film samples are investigated. Two groups of representative samples, uterine myoma patients (control group 1) and patients with external genital endometriosis (study group 2), were considered. We applied a complex algorithm of analytical data processing-statistical (1stand 4th central statistical moments), correlation (Gram-Charlie expansion coefficients of autocorrelation functions) and fractal (fractal dimensions) parameters of polarization-correlation parameters maps. Objective markers for diagnosing extragenital endometriosis were found.
