Abstract

Dye-doped liquid crystals have been recently recognised as new recording materials potentially for a variety of applications including optical correlation, novelty filtering, phase conjugation and holographic storage. In this paper we describe a class of liquid crystals doped with organic dyes showing optical storage, readout, and erasure capabilities. We discuss the hologram recording mechanism in this system which is different from already known ones for liquid crystals and compare it with mechanisms elaborated for photorefractive polymers and crystals. We show examples of application of liquid crystals for a real-time holography purposes.
