Polarization-Sensitive Recording Media Based on Fluorophore (Lucifer Yellow) Dye for Holography

摘要

Polarization-sensitive hologram media based on polyvinylpyrrolidone and gelatin matrices, into which the Lucifer Yellow and Coumarin 466 dyes have been introduced, have been created. A Denisyuk multiplex dynamic hologram has been recorded using linearly polarized LSR 405 NL-50 laser radiation (lambda = 405 nm) in a luminescent photoanisotropic gyrotropic material. The photoanisotropic characteristics of the beam corresponding to the reconstructed virtual image of the object field have been measured by polarization-luminescent holography. The polarization spectra and photoluminescence intensity spectra of the reconstructed image have been measured, depending on the recording medium composition. The possibility of multiplex recording and observation of several images of an anisotropic gyrotropic object simultaneously if they are encoded by different emission frequencies and/or polarization state, has been shown. The combination of nondestructive polarization-luminescent holographic measurement method with other luminescent spectroscopic methods significantly expands the scope of this method and dramatically increases the overall information content of the study.
