Abstract

A novel technique is proposed for creating stacked CGVHs (computer-generated volume hologram) that reconstruct full-color holographic 3D images in full-parallax. Because of excellent wavelength selectivity of volume holograms, the stacked CGVHs can reconstruct high-quality images with white illumination. However, it is not easy to expand the size of stacked CGVHs due to limited output power of the laser, used for contact-copy to transfer the 3D images of printed high-definition CGHs (computer-generated hologram) to CGVHs. In this paper, we propose a method referred to as tiling contact-copy for extending the size of CGVHs. Using the technique, the size of a fabricated CGVH is no longer depending on the laser power. We demonstrate a full-color stacked CGVH over 10 cm × 10 cm, fabricated by the proposed technique.
