摘要： A hologram copying system that includes a first reconstruction beam, a second reconstruction beam that is incoherent with respect to the first reconstruction beam, a first master hologram responsive to the first reconstruction beam for producing a first diffracted beam, a second master hologram responsive to the second reconstruction beam for producing a second diffracted beam, and a holographic recording layer responsive to the first and second reconstruction beams and the first and second diffracted beams, whereby a first hologram is formed by interference of the first reconstruction beam and the first diffracted beam, and a second hologram is formed by interference of the second reconstruction beam and the second diffracted beam.

摘要： A method is disclosed for making holograms on transparent surfaces. A protective thin substrate 18 is laminated to a temporary support 24 for processing. This procedure protects the delicate thin substrate 18 through the processing steps. Upon completion of the processing steps, the thin substrate 18 is then removed from the temporary support 24. The applied photosensitive material gives the delicate thin substrate 18 added strength. The thin substrate 18 is then laminated to the final surface 26. In one embodiment, the final surface 26 corresponds to a car windshield 34. Playback lamps 36 located in the dashboard 32 illuminate the thin substrate 18 to read the holographic image.
