Principal research accomplishments:

• Developed method of holographic measurement of dynamic and structural characteristics of quasi-spherical Brownian particle ensembles.

• Developed practical interference correlometry methods for characterization of rough surfaces. Method has sensitivity threshold in the tens of Angstroms.

• Application of fractical geometry and fractal optics, along with fast polarization-interference methods, to rough surface diagnostics.

• Investigation of referenceless holographic recording methods for fractal analysis.

• Introduction of new approach for analysis of singularities (e.g., phase-difference vortices) in vector fields. Included in this work is the formulation of the sign principle for phase-difference vortices and the elaboration of an inteferometric technique for the analysis of s-contours and C-points in vector optical fields.

• It is shown that the result of colouring of the beam at the output of the scattering medium depends on the magnitudes of the phase delays of the singly forward scattered partial signals. The colouring mechanism has for the first time experimentally been illustrated for a forward propagating beam through a light-scattering medium. Spectral investigation of the effects of colouring has been carried out using a solution of liquid crystal in a polymer matrix. The amplitude ratio of the non-scattered and the singly forward scattered interfering components significantly affects the colour intensity. It has further been established that the spectral content of the illuminating beam strongly influences the colour of the resulting radiation.

• The internal energy flow in a light beam can be divided into the “orbital” and “spin” parts, associated with the spatial and polarization degrees of freedom of light. In contrast to the orbital one, experimental observation of the spin flow seems problematic because it is converted into an orbital flow upon tight focusing of the beam, usually applied for energy flow detection by means of the mechanical action upon probe particles. We propose a two-beam interference technique that results in an appreciable level of spin flow in moderately focused beams and detection of the orbital motion of probe particles within a field where the transverse energy circulation is associated exclusively with the spin flow. This result can be treated as the first demonstration of mechanical action of the spin flow of a light field.

• A new approach is proposed for estimating the degree of coherence of optical waves. The possibility of transformation of the spatial polarization distribution in the measured spatial intensity distribution for determining the degree of correlation of superposing waves, linearly polarized in the plane of incidence, is shown.
