1. A method for encrypting a holographic image, comprisingproducing a beam of light having at least two wavelengths of light;

  • splitting the beam of light into an illumination beam and a reference beam;

    adding amplitude information to the illumination beam with an intensity control device to form an object beam;

    selecting wavelength information in the object beam to form a spatial color modulated object beam; and

    directing the reference beam and the spatial color modulated object beam to a predetermined location on a holographic media to enable the reference beam and the spatial color modulated object beam to form an interference pattern on the holographic media.
