Поляризационно-чувствительные регистрирующие среды для голографии на базе красителя--флуорофора lucifer yellow

Abstract

Polarization-sensitive hologram media based on matrices of polyvinyl pyrrolidone and gelatin are created, containing Lucifer Yellow and Coummarine 466. A multiplexed dynamic hologram of Denisyuk is recorded in a luminescent photoanisotropic gyrotropic material, using linearly polarized radiation of the laser LSR 405 NL-50 (= 405 nm). Using the method of polarization-luminescent holography, the photoanisotropic characteristics of the beam have been measured corresponding to the reconstructed imaginary image of the object field. The polarization spectra and photoluminescence intensity spectra of the reconstructed image were measured, depending on the composition of the recording medium. The possibility of multiplex recording has been demonstrated, as well as simultaneous observation of several images of an anisotropic-gyrotropic object encoded by different emission frequencies and / or polarization state. The combination of non-destructive polarization-luminescent holographic measurement method with other luminescent spectroscopic methods significantly expands the scope of this application by increasing dramatically the overall information content of the study.
