Abstract

A computer-generated hologram (CGH) is well-known to reconstruct 3D image truly, and several CGH printers are reported. Since those printers can only output a transmission hologram, the large-scale optical system is necessary to reconstruct the full parallax and full color image. As a method of a simple reconstruction, it is only necessary to use a volume reflection hologram. However, the making of a volume hologram needs to transfer a CGH by use of an optical system. On the other hand, there are the printers which output volume type holographic stereogram reconstructing the full parallax and full color image. However, the reconstructed image whose depth is large gets blurred due to the insufficient sampling rays of a 3D object. In this study, the authors propose the volume hologram printer to record the wavefront of a 3D object. By transferring the CGH which is displayed on the LCoS, the proposed printer can output a volume hologram. In addition, the large volume hologram can be printed by transferring plural CGH that recorded partial 3D object in turn. As a result, the printed volume hologram has been able to reconstruct a monochrome 3D image by white light, and realized the full parallax image.
