Diagnostics of luminescent recording media based on the polarized scattering spectra of hologram sensors formed in the substance analyzed

Abstract

The article is devoted to the diagnosis and identification of luminescent holographic information carriers in particular wine products using polarization holographic spectroscopy methods. For the first time, to our best knowledge, a technique has been developed for measuring and analyzing scattered polarized light (depolarization spectra) on polarization-holographic sensors formed in analyte. Polarized scattering spectra on a hologram sensor (measuring transducers) are of particular interest, since they provide information not only about the chemical composition of the media, for example, luminescence and absorption spectra, but also about particles that may be present in the analyte – the higher the anisotropy of the molecules and atoms, the greater the depolarization. Methods for measuring polarized scattering and excitation spectra carried out for various samples of holographic materials, as well as methods for processing and presenting the obtained spectral data are described. This may be of interest, since recording media, in particular wine, are complex colloidal systems. For the diagnosis, classification and identification of recording materials, it is proposed for the first time to use reflective holographic sensors (Yu.N. Denisyuk) of various physical natures (the concept of a spectral holographic portrait).
