Abstract :
In this article we present results of studies on dynamic holography in a hybrid nematic liquid crystal panel with photo-conducting polymer. Studies were done in a typical degenerated two wave mixing experimental set-up (DTWM). We present results of diffraction efficiency evolution and its dependency on grating period. We also propose mathematical models for quantitative and qualitative description of this phenomenon, based on three gratings coupling. Comparison of theoretically obtained curves with experimental results have shown good agreement.
