CROSS-TALK IN MULTIPLEXED HOLOGRAMS USING ANGULAR SELECTIVITY IN LINBO3

The angular selectivity of volume holograms stored in LiNbO3 is charac terized as a function of the writing angle and the refractive index mo dulation depth. Using this selectivity and changing the orientation be tween the crystal and the writing beams several image holograms are st ored. An experimental study of the cross-talk between consecutive holo grams as a function of the recording angular separation is also presen ted. A criterion for the optimum angular separation between consecutiv e holograms for highest storage capacity is obtained.
