Volumetric-image forming system and method thereof

摘要

A volumetric-image forming system comprises an optical image-forming means 15 and a volumetric display apparatus 17, the optical image-forming means 15 having light-transmitting and plate-like first and second reflecting members 13 and 14 respectively provided with belt-like first and second reflecting surfaces 11 and 12, the first and second reflecting surfaces 11 and 12 being arranged perpendicular to a plate surface and in parallel at a constant pitch, the first and second reflecting surfaces further being arranged crossing one another, the volumetric display apparatus 17 being arranged in the back side of the optical image-forming means 15 and displaying a luminous volumetric image A in a resting or dynamic state inside a display apparatus 16 from electronic data, whereby a volumetric image A inside the display apparatus 16 is formed as a volumetric image B in a free space in the front side of the optical image-forming means 15.

1. A volumetric-image forming system, comprising:
an optical image-forming means, the optical image-forming means comprising:
a light-transmitting and plate-like first reflecting member, the first reflecting member having first reflecting surfaces arranged perpendicular to a plate surface of the first reflecting member and also arranged in parallel at a constant pitch; anda light-transmitting and plate-like second reflecting member arranged closely or in direct contact with the first reflecting member and arranged on a level that is different from the level of the plate-like first reflecting member, the second reflecting member having second reflecting surfaces arranged perpendicular to a plate surface of the second reflecting member and also arranged in parallel at a constant pitch,wherein the first reflecting surfaces and the second reflecting surfaces are arranged crossing one another in a planar view; and a volumetric display apparatus arranged in the back side of the optical image-forming means and displaying a luminous volumetric image A in a resting or dynamic state inside a display apparatus from electronic data, wherein the volumetric display apparatus comprises:
a projector portion and the display apparatus, the projector portion projecting images by transforming image signals formed from electronic data into images, the display apparatus having electronic screens displaying the images and arranged in the projection direction of the images with a distance between each electronic screen, the electronic screens electronically controlling light to select the state of light between transmitting state and scattering state, wherein an image of the volumetric image A inside the display apparatus is formed as a volumetric image B in a free space in the front side of the optical image-forming means, and wherein each of the first reflecting member and second reflecting member is an N-layered structure composed of two or more layers, wherein the positions of adjacent first reflecting surfaces of the N-layered first reflecting member when viewed in a planar view are shifted by 1/N of the constant pitch of the first reflecting surfaces; and wherein the positions of adjacent second reflecting surfaces of the N-layered second reflecting member when viewed in a planar view are shifted by 1/N of the constant pitch of the second reflecting surfaces.
