摘要：

The 90-degrees geometry - with reference and signal beams entering orthogonal crystal faces - is used to angularly multiplex up to 500 holograms at each of 8 spatially multiplexed locations in a LiNbO3 crystal. A segmented mirror array and a 2D mechanical scanner are used to perform both angular and spatial multiplexing. We show that this mirror array can be used with non-mechanical angle scanners, providing for holographic storage in multiple locations with no moving parts.
