The work consists of investigation results of diagnostic efficiency of a new azimuthally stable Mueller-matrix method of analysis of laser autofluorescence coordinate distributions of biological tissues histological sections. A new model of generalized optical anisotropy of biological tissues protein networks is proposed in order to define the processes of laser autofluorescence. The influence of complex mechanisms of both phase anisotropy (linear birefringence and optical activity) and linear (circular) dichroism is taken into account. The interconnections between the azimuthally stable Mueller-matrix elements characterizing laser autofluorescence and different mechanisms of optical anisotropy are determined. The complex statistic, correlation and fractal analysis of coordinate distributions of such Mueller-matrix rotation invariants is proposed. Thereupon the quantitative criteria (statistic moments of the 1st to the 4th order, correlation moment, fratal parameters) of differentiation of histological sections of uterus wall tumor – group 1 (polypus) and group 2 (adenocarcinoma) are estimated.
The correlation between the topological and the statistical approaches to describe inhomogeneously polarized optical
fields is considered. Two main models describing coordinate distributions of polarization parameters within the topological
approach, viz. the "island" model and the "toy-in-toy" one are experimentally proven. It is shown that the correlation
length of polarization parameters of the field is comparable with the mean distance between points with orthogonal states
of polarization.
The paper deals with investigating different rough surface structure obtained by using classical processing techniques. It

We analyze and experimentally test the concept of laser polarization biotissue probing. The methods of increasing the SNR 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 SNR is investigated. The possibilities of polarization correction of the probing beam for contrasting biotissue images are analyzed.

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.

A method of polarization phase reconstruction of BT architectonics was suggested.
New feasibilities are considered for optical correlation diagnostics of rough surfaces with different distributions of irregularities. The influence of deviations of the height surface roughness distribution from a Gaussian probability distribution on the accuracy of optical analysis is discussed. The possibilities for optical diagnostics of fractal surface structures are shown and the set of statistical and dimensional parameters of the scattered fields for surface roughness diagnostics is determined. Fast operating measuring devices for roughness control are proposed.
The multifractal description of rough surfaces is discussed and the mechanisms for analysis of fractal and multifractal height distributions of inhomogeneities for rough surfaces are simulated. The original technique for estimating the spectrum of singularities is proposed for studying these distributions. Further, the application of the wavelet analysis for quantitative characterization of fractal distributions associated with rough surfaces and for determination of the position of singularities of these structures is presented.
