ABSTRACT:
A method of making a holographic device comprising sensitizing a plurality of layers and stacking the layers to form a composite structure. Each layer is sensitized to at least one color wavelength. The method further includes directing at least two laser beams at the composite structure. Each of the laser beams is oriented at an angle with respect to an incident surface of the composite structure such that the laser beams intersect one another within one of the layers of the composite structure. The laser beams are moved along the layer to create interference patterns in the sensitized layer.
