摘要:
The present invention provides a method and apparatus for producing a hologram from a series of two-dimensional images horizontally different in line of sight from each other. The holographic apparatus employs original images produced by photographing an object from different directions, an object optical system which makes a light be incident upon original image to project an object beam onto photo-sensitive material, and a reference optical system which projects a reference beam of a same wavelength as the object beam toward the photo-sensitive material. The horizontal component of the object beam can be converged at a rear point i.e., a point of view at image reproduction, relatively distant from the photo-sensitive material on which a hologram is produced. When the hologram is reconstructed, a beam having the same wavelength as when recorded is converged at the rear point of view, so that the reconstructed image can be viewed in a same color free from any color shading.
