Numerical simulation demonstrates fast computer-generated hologram calculation via zone plate circular symmetry, highlighting scalable rendering for three-dimensional displays.
Computer-Generated Holograms (CGHs) can be generated from three-dimensional objects composed of point light sources by overlapping zone plates. A zone plate is a grating that can focus an incident wave and it has circular symmetry shape. In this study, we propose a fast CGH generating algorithm using the circular symmetry of zone plates and computer graphics techniques. We evaluated the proposed method by numerical simulation.
