Abstract

In this paper we present results of theoretical and experimental research of dynamic holographic system based on optically-addressed liquid crystal light modulator inside optical feedback loop, which provides asymmetrization of grating's profile. We use computer-based signal loop instead of pure optical link. This approach gives us solution for hysteresis problems and significantly reduces optical scheme complexity.
