Abstract
The electrooptic effect in ferroelectric materials allows volume phase holograms and two-dimensional images to be stored as a spatial distribution of electric charge density. The kinetics of the build up of the photo-induced space charge field is analyzed for the general case of nonuniform illumination. The nonuniformity of light gives rise to the fatigue phenomenon observed during multiple hologram storage or when several hologram write–read/erase cycles are performed. This phenomenon is analyzed and discussed in the model we present. In image storage applications, the nonuniformity of light is shown to introduce nonlinearities in the recorded image at large exposures. The nonlinearity however, can be reduced by flooding the electrooptic material with strong uniform illumination during the storage process.
