Holographic 3D color printer

Abstract

Holographic 3D color printer is one of ideal three-dimensional display apparatuses. To obtain distortion free and full-parallax three-dimensional image, two-dimensional images which have horizontal and vertical parallaxes should be printed into very small elementary holograms. Furthermore, by recording Lippmann type hologram, the image can be reconstructed by a white light source. The elementary holograms is partitively recorded by R, G, B Laser. So, the reconstructed image can be observed with true color. The light reconstructed from holographic recording material BB-PAN is shifted to shorter wavelength than recording wavelength.
