Abstract
A nonuniform photovoltaic field is created in Fe:LiNbO3 during hologram recording exposures. Experimental results and analysis show the degradation of the volume holograms in the presence of the photovoltaic field. A sodium chloride solution is used to short-circuit the crystal to improve the stored- image quality. Experimental results to demonstrate the effectiveness of the proposed method are presented.
