Abstract : This paper presents a novel real-time hologram recording method and derives a formula for calculating the diffraction efficiency of gratings recorded in phase change media. The formula gives media parameters for high diffraction efficiency. In addition, a two-dimensional character pattern is successfully reconstructed using GeTe alloy film.
