Qualitative Analysis of Wine and Wine Materials by Polarized Luminescent Holography Methods Based on the Use of Their Optical Polarization Spectra

Abstract

Wines have been identified and classified on the basis of joint processing of various types of polarization spectra of Denisyuk multiplex dynamic luminescent holograms obtained from samples of studied wine products (specific wine brands). The luminescence spectrum of the restored imaginary image of the object, spectrum of the degree of anisotropy of the luminescence of the object reconstructed field, and spectrum of the ellipticity coefficient of the luminescence of the object reconstructed field have been selected for the analysis. An experimental study of the polarization properties of Denisyuk multiplex holograms obtained in a luminescent photonisotropic–gyrotropic material using a linearly polarized coherent light source has been conducted. Polarization-holographic memory has been observed. An experiment on the identification of samples that was conducted to test the possibility of using polarization spectra for wine recognition has been described.
