Paper Abstract

This paper describes the use of a numerical simulation topredict the dynamic behavior of a photorefractive crystal exposed tointerfering light waves at two different frequencies. Unlike staticrecording media, photorefractive materials allow for the simultaneousdiffraction from and generation of refractive index gratings. Thegrating properties are evaluated in terms of their effect on theperformance of a dynamic distributed sensor which uses the crystal as aholographic recording medium. Experimental results are presentedwhich support the behavior predicted by simulation.
