The article describes the qualitative analysis of wines and wine products using polarization-luminescent holography methods. Identification and classification of wines is carried out on the basis of combined processing of various types of polarization spectra of multiplex reflective luminescent holograms of Denisyuk, obtained from the analyzed samples of the wine products (specific brands of wine). The following types of optical spectra of dynamic holograms were selected for analysis: 1) spectral intensity distribution of polarized luminescence (parameter-I); 2) the spectral distribution of the degree of anisotropy of luminescence (parameter-r) and - the ellipticity coefficient (Ce parameter) of the luminescence of the reconstructed virtual image of an object (object beam). An experimental study has been performed of the polarization properties of a reflective hologram Denisyuk, obtained in a luminescent photoanisotropic-gyrotropic material using a linearly polarized coherent light source. The dependence of the polarization state of the reconstructed image on the polarization of the recovering beam (polarization-holographic memory) is observed.An experiment is described on the investigation of samples, conducted to verify the possibility of using polarization spectra for identification of wine. Not individual fragments of the spectra are processed, as when using scalar spectroscopy methods and vector spectra as a whole, which increases the information content and reliability of the analysis. The results presented in the article can serve as the basis for creating guidelines, using spectral-holographic “portrait” of specific brands of wine, according to the set of characteristic features. This will allow revealing the authenticity of wine products, including such properties as variety composition of the annual harvest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
