Under the limited condition, interference patterns with a spherical reference wave do not vary well between a cylindrical hologram and a polygonal hologram. However, since their calculation algorithms are different, the total calculation time and memory usage depend on them. In this study, to verify this assumption, numerical simulation was performed. As a result, similar holograms and their reconstructed images were obtained whereas there was a difference on calculation performance.
