【 摘 要 】

We propose a large-scale hologram calculation using WAvelet ShrinkAge-Based 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 x 65, 536 pixels and a pixel pitch of 1 mu m. The hologram calculation time amounts to approximately 354 s on a commercial CPU, which is approximately 30 times faster than conventional methods. (C) 2017 Elsevier B.V. All rights reserved.
