This work is aimed at generalizing the methods of laser polarimetry in the case of partially depolarizing optically anisotropic methyl acrylate layers. A method of differential Mueller-matrix mapping is proposed and substantiated for reproducing the distributions of the parameters of linear and circular birefringence and dichroism of partially depolarizing methyl acrylate layers.
A method of 3D Mueller-matrix reproduction of the distributions of the parameters of linear and circular birefringence and dichroism of partially depolarizing methyl acrylate layers is proposed and substantiated. The dynamics of the change in the value of the statistical moments of the 1st - 4th orders characterizing the distributions of the optical anisotropy parameters of the polycrystalline structure of the partially depolarizing methyl acrylate layer in various "phase" sections of its volume is investigated and analyzed.
A collection of layered maps of the depolarisation due to diffuse layers of polyvinyl acetate are produced using a polarization-holographic Mueller matrix method approach. The topography of maps of the diffuse layers of polyvinyl acetate relates to the scattering multiplicity within the volume and the specific of polycrystalline structure. The overall depolarisation map is a convolution of the effects of these two factors. Through statistical analysis, the dependences of the magnitudes of the first to fourth order statistical moments are determined. These moments characterise the changing distributions of the depolarisation values through the volume of diffuse layers of polyvinyl acetate with different concentration. Dehydrated polyvinyl acetate layers depolarisation maps are characterised by larger average and dispersion, and less skewness and kurtosis, compared to the distributions for the diffuse "dehydrated" layers of polyvinyl acetate. This work demonstrates that a polarization-holographic Mueller matrix method can be applied to the assessment of the 3D morphology of diffuse layers of polyvinyl acetate, with applications in diagnosis – differentiation of the degree of adhesion.
