Abstract: AbstractWe propose a large-scale hologram calculation using WAvelet ShrinkAgeBased superpositIon (WASABI), a wavelet transform-based algorithm. An image-type hologram calculated using the WASABI method is printed on a glass substrate with the resolution of 65, 536×65, 536 pixels and a pixel pitch of 1µm. The hologram calculation time amounts to approximately 354 s on a commercial CPU, which is approximately 30 times faster than conventional methods.
