In this paper we propose a novel method to perform multiplexing. In our setup, we use only one beam of light to illuminate and pass through the object pattern and to image it into a photorefractive lithium niobate crystal. Image information is recorded in the crystal in the form of gratings due to fanning effect. We can read the image information using another collimated or white-light reading beam. To record multi-images in the same crystal, the object beam of each recording should be tilted to the last object beam for avoiding crosstalk. As a result, we can record multi-images in a lithium niobate crystal, and read them separately without crosstalk.
