title: Real time hologram reinforcement demonstrated by thionine/PVA photoreducible thin layers.
abstract: Thionine dye dissolved in polyvinylalcohol matrix is a well-known photoreducible system that shows photochromism. Experiments on a real time hologram recording process performed by this system are presented here. During the reading process, a grating reinforcement was observed, and this phenomenon is qualitatively discussed.
