This paper describes enlargement of the viewing zone angle in a hologram sampled by pixels. If the angle between the object beam and the reference beam is larger than the angle determined by the sampling period on the hologram plane, aliasing occurs in the fringe patterns. First, we demonstrate that high order diffraction beams reproduced from fringe patterns containing aliasing components can be equivalent to original object beams. Next we propose a method by which the angle of the viewing zone can be enlarged by combining these high-order reconstructed beams from the fringe patterns with aliasing. Finally, we confirm the effectiveness of the proposed method in an optical experiment which temporally, combined these high-order reconstructed beams.
