The features of the use of polarized radiation in the problems of metrology of optical-geometric and structural parameters of light-scattering objects of various physical and chemical nature are described. Experimental situations are revealed that are most relevant for the study of optically anisotropic dispersed media containing particles of various shapes, sizes and orientations. The analytical dependence of the value of the fourth Stokes parameter of circularly polarized radiation passing through a layer of oriented particles with an optical thickness τ < 3 on the degree of their orientation is determined. A method is proposed for assessing the degree of orientation of macromolecules in polymer films, the conformation of biopolymers from the values of f22 components at any scattering angles, and determining the shape of macromolecules at scattering angles greater than α > 30°. Experimental conditions and methods of matrix polarimetry of the process of corrosion of the free surface of a metal and its corrosion under a paint-and-lacquer coating are presented.

At present, liquid crystals – polymer (LC-P) composites such as polymer-dispersed liquid crystals (PDLC), polymer stabilized liquid crystals (PSLC) and polymer networks in liquid crystals (PNLC) are widely used as operating elements of optical devices such as microlens and elements, whose principle of operation is based on light scattering. LC-P composites light refraction features depend on shape and size of liquid crystal (LC) drops as well as on director orientation inside of drops. LC anisotropy influences polarization characteristics of refracted radiation. We have investigated desined as the tunable microlens on LC-P with different components concentration ratio. We have used LC E7 by Merck, dispersed in the polymer NOA 65 by Norland Inc. as the object of research. They have close refractive indeces which provide the posibility to shange the focal length of such LC lens in wide range. We change focal length by change of applied voltage and by rotation of polarization plane of illuminating beam. Partial beams passed through LC droplets and polymer matrix may be considered as plane waves passing different optical pathes and interfering in the far zone. Changing the voltage results in changing the LC effective refractive index leading to a change of the path difference between the interfering beams. The effect of interference decreases of some spectral components of the radiation passing through LC-P sample can be used as a tunable chromatic lens.

Optical Speckles has many extraordinary applications like subwavelength focusing, aberration-free imaging, etc. which are not possible even with a highly coherent optical field. This makes it necessary to study the fundamental properties of such Optical Speckle fields. In the recent past, the polarization correlation vortex phase was experimentally realized in vector speckle field generated by scattering of Poincare beam. Higher-order correlations have also been studied in such vector speckle fields. Moving further into this direction, we have studied the first-order polarization correlations in the focused vector speckle field. We have generated a vector speckle field by scattering of Poincare beam. Which is then allowed to be focused using a spherical and a cylindrical lens. The focused vector speckle field intensities at different planes around the focal plane were recorded to get polarization correlations at each plane. It was observed that the charge of the input vortex beam before scattering is still present in the polarization correlation of the focused vector speckle field. We have also observed charge inversion of polarization correlation vortex focused through a cylindrical lens. The importance of this study relies in the fact that it provides, with supporting experimental and simulation results, that the polarization correlation obeys the wave equation. It could find application in optical image processing while analyzing any optical data, to find information about the source of the speckles, etc.

Crystal and magnetic domain structures of iron garnet films with different thicknesses are studied by means of atomic and magnetic force scanning microscopies as well as by means of high-resolution Х-ray diffraction. The model of the garnet films as a set of vertical columns with certain lateral sizes is proposed and substantiated. Within this model, X-ray intensity distributions in the vicinity of the reciprocal lattice points are calculated using the Monte Carlo approach to determine densities of two dislocation types with different Burgers vectors.

The paper describes the stabilizing effect of random phase diffuser applied at recording or synthesis of Fourier hologram. The stabilizing effect is meant here as ability to keep quality of the image formed by Fourier hologram or kinoform in terms of preserving the main structure of intensity distribution under wavefront distortions of different scale in restoring beam. A theoretical explanation to the effect is given as converting of convolution of ideal image with hardware function of the system from coherent to non-coherent. Demonstrated are the results of computational and real experiments with synthesized Fourier hologram and SLM device. A test random wavefront distortion is taken for the experiments. Stabilization is demonstrated for the scale of distortion as large as approximately 5π of amplitude.

A Sagnac interferometer’s ring structure enables counter propagating light modes to periodically encounter the same optical elements, effectively simulating infinite periodic potential of a one dimensional crystal. This discrete translational symmetry causes the dispersion of counter propagating beams to acquire a band structure. The band gap between modes arise when their degeneracy is lifted by introducing non-reciprocal effects such as rotation of the interferometer which breaks the time reversal symmetry for all but certain discrete values of angular rotation frequencies at which the two bands cross each other. The coupling between counter propagating modes is examined in a two dimensional state space. We study the interplay between these optical level crossings and Berry curvature to show the accumulation of wave vector dependent Berry phase

In the paper described is a method of transmission of phase information by an optical signal which propagates through an optically inhomogeneous medium. Phase information is represented as an interference pattern of two states of an object that is deformed between state fixations. It is proposed to pass signal and reference beams through an optically inhomogeneous path in the same direction when recording holograms of states. In this implementation, an optical signal which carries information in the form of a system of interfering beams (holograms) is subject to minimal interference. And these holograms contain undistorted information about the wavefronts of the beams. Further mathematical processing (image addition and noise separation) allows to obtain the desired information about the deformation of the object. Optical inhomogeneities in the work are represented in thin diffuser approximation (Random Phase Diffuser), where RPD is described as an ensemble of point retranslates. Each of these retranslates at any point of the cross section of the beam transmit the amplitude of the field and at the same time adds a random stationary change to the phase. This model of optical inhomogeneities is of practical interest, because such a representation corresponds to the description of a single-mode regular fiber bundle, which can be used in real experiments to obtain information about the state of the object from hard-to-reach places.

In this paper, we study a three-dimensional Lorenz system that demonstrates chaotic behavior. We present the state equations and mathematical analysis of the system. We use a system-design platform, like LabView, to study and analyze main information properties, such as chaotic attractors, time series, bifurcation diagram, and dynamic behavior of the overall system. We implemented an Arduino Uno based design to display chaotic attractors of the Lorenz system. The Arduino is connected to a computer through the USB port, while graphs were uploaded using program software ArduinoIDE. Finally, the connection scheme and programming code are also presented.
