摘要: Multiple layers (12) of holographic exposures and methods for preparing multiple layers (12) of holographic exposures are described. The multiple layers (12) of holographic exposure combine to form holographic stacks (10) and are fabricated from layers (12) of exposed and processed photosensitive recording films, each of which having at least one independently recorded hologram. The holographic stacks (10) are useful for providing wide bandwidth holograms and holograms having superimposed images (Fig. 1).

摘要: A holographic stoplight assembly including a volume hologram having a recorded stoplight image secured adjacent to the inside surface of an automobile window. The volume holgoram is selectively illuminated by an illumination source located out of the driver's rearward field of vision and forward of the hologram. Also disclosed is a method for recording a hologram for use in a holographic automobile stoplight system which includes the steps of recording the image of a stoplight in a first hologram, and then recording in a second hologram the playback image of the first hologram.

摘要: Photosensitive films (20) which are protected by suitable barrier materials (32) are described. The protective barriers (32) form a film on at least one surface (30) of a layer of photosensitive material (26) and the protective barriers (32) are water soluble polymeric materials having a refractive index similar to the refractive index of the recording film (20). The protected photosensitive recording films (20) are useful for recording high efficiency holograms on photopolymers in the presence of index matching immersion oils.

摘要: An encoded hologram (11) that produces a first image (I1) and a second image (I2) pursuant to playback illumination is provided, wherein the first image (I1) is resolvable by human vision while the second image (I2) is not resolvable by human vision when the playback illumination comprises non-coherent broad band illumination, and wherein the second image (I2) is machine readable when the hologram (11) is illuminated with playback illumination that is based on the original reference beam (PB2).

摘要: A head-up display for a vehicle, including a primary image reflection hologram (11) supported by a transparent substrate located in the vehicle operator's field of view for the ambient scene in front of the vehicle, a light source (17) for providing playback illumination to the primary image hologram, and a guard hologram (13) in front of the primary image hologram (11) for substantially reflecting ambient illumination that otherwise could spuriously turn on the first reflection hologram, the guard hologram (13) having an angular bandwidth and a spectral bandwidth that are greater than the angular bandwidth and the spectral bandwidth of the primary image hologram, and having an optical density of 2.0 or greater. The guard hologram can be parallel fringe reflection hologram or a slant fringe reflection hologram.
