Abstract

We propose a flexible-ratio adaptive point-spread spherical wave synthesis method for fast computer-generated hologram calculation. The conventional adaptive point-spread algorithm uses a fixed ratio between the major and minor axes of the point source, whereas the proposed method uses flexible-ratio sources, i.e., ellipses, for more effective calculation. Numerical simulation was conducted to validate the proposed method. The results show that the proposed method has the potential to achieve faster calculation, compared to the calculation in conventional methods, without significant image degradation.
