Abstract
It is necessary for practical holograms to be a large reconstructed image and wide viewing area. We have been studying the computer-generated rainbow hologram and long printing time of the calculated hologram is one of the problems. The optical transfer overcomes this problem while advantages of the computer-generated hologram are maintained. Rainbow hologram is optically transferred from the computer-generated master hologram. We have demonstrated that the total fabrication time is reduced to one sixth with the proposed method.
