Abstract
A color photographic hologram system is provided. The reference light wave is incident to the film at a fixed reference beam angle. By adjusting an included angle between the object light wave corresponding to respective monochromatic component images and the reference light wave, the reference light wave and the object light wave are interfered with each other to result in a plurality of interference fringes on the film. When a white light is projected on the film, the reconstructed image shows the color effect.

A color photographic hologram system, comprising:
- an illumination unit for providing a coherent beam;
- a beam splitting unit for splitting said coherent beam into a reference beam and an object beam;
- a reference beam processing unit for receiving said reference beam and outputting a reference light wave with respect to said reference beam;
- an image generating unit for providing a first monochromatic component image and a second monochromatic component image of at least one image, wherein a first monochromatic color of said first monochromatic component image is different from a second monochromatic color of said second monochromatic component image;
- an object beam processing unit comprising an angle adjustable element in response to said first monochromatic color and said second monochromatic color, respectively, said object beam processing unit guiding said object beam from said beam splitting unit to said image generating unit and then generating an object light wave after said object beam passes through said image generating unit and said angle adjustable element;
- and
- a film, wherein said reference light wave is incident to said film at a fixed reference beam angle, and said object light wave is incident to said film at an included angle between said object light wave and said reference light wave, so that said reference light wave and said object light wave are interfered with each other to result in a plurality of interference fringes of two-dimensional areas respectively with respect to said first monochromatic component image and said second monochromatic component image on said film, wherein said included angle corresponding to said first monochromatic component image is different from said included angle corresponding to said second monochromatic component image, and at least a portion of said interference fringes of said two-dimensional area with respect to said first monochromatic component image is overlapped with a portion of said interference fringes of said two-dimensional area with respect to said second monochromatic component image.
