Efficient digital hologram generation using reflection symmetry of principle fringe pattern

Recently a novel look-up table (N-LUT) method to dramatically reduce the number of pre-calculated interference patterns required for generation of digital holograms was proposed. In this method, principle fringe pattern (PFP) has reflection symmetry in geometry. Thus in this paper, we proposed the memory reduction method using this reflection symmetry of PFP. From some experimental result, the memory could be reduced by 50%.
