A holographic display is a realistic three-dimensional (3D) display because it produces an exact copy of the wave front of scattered light from 3D objects. It demands a wide viewing angle for 3D visualization. However, the viewing angle of holographic displays based on conventional spatial light modulators (SLMs) is less than 3°. The pixel pitch of conventional SLMs is in the range of 10-100 μm. Recently, we have fabricated a two-dimensional pixel array with sub-micrometer-scale pixels for a wide-viewingangle holographic display. The pixels were driven by a thermomagnetic recording system using a metal mask that formed fringe patterns. However, the reconstructions of 3D images were ixed. In this paper, we describe the results of the reconstruction of any 3D images using a tilling optical addressing method. The tilling optical method reproduced any magnetic fringe pattern with 5 × 107 pixels for the reconstruction of 3D images.
