Abstract

Two azo dyes were introduced in polyvinyl alcohol matrices giving thin solid colored films on which they can record polarization volume holograms in real time. These new azo dye polymer photosensitive systems have been holographically studied. Holographic characterization was investigated to determine its optimal and dynamical recording application conditions. Under a light exposure of 300 mJ/cm², polarization volume real time holograms having 0.27% diffraction were produced. We present three simple uses based on the facts that these photosensitive films are erasable and reusable for many thousand write/read/erase cycles and that they may show a memory effect in specific conditions.
