Abstract: Provided is a hologram generation method including receiving a distribution of a polygon and generating an angular spectrum based on the distribution of the polygon, determining whether a rotation angle of the polygon is included in a first section determined based on a maximum diffraction angle of a spatial light modulator, and recording the angular spectrum if it is determined that the rotation angle is included in the first section.
