    摘要: A disk cover is provided with a reflection-type hologram assembly having multiple exposure images therein. The sun or an artificial light source illuminates the hologram assembly as it rotates as a result of the body moving. The exposure images are successively reconstructed to produce a single image that may be remotely positioned from and stationary relative to the rotating disk cover.

    摘要: A system for monitoring intensity before, during, and after holographic exposure includes a monitoring assembly within an exposure beam and intermediate a light source and a hologram recording assembly. With the monitoring assembly in the exposure beam, a monitoring beam is produced that is directed towards detection elements located outside of the exposure beam. At the same time, the monitoring assembly allows the exposure beam to pass therethrough and onto the hologram recording assembly. The monitoring assembly may include a reflection hologram with an effective shape which is different from the supporting substrate, or glass substrates with an internal reflecting surface. In either event, the exposure beam remains undistorted. The spatial arrangement among the light source, hologram recording assembly, and detection elements are such that a reflected beam from the hologram recording assembly is directed away from the detection elements to avoid incorrect intensity monitoring.

    摘要: A head-up display for a vehicle, including a primary image reflection hologram 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 for providing playback illumination to the primary image hologram, and a guard hologram in front of the primary image hologram for substantially reflecting ambient illumination that otherwise could spuriously turn on the first reflection hologram, the guard hologram 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.

    摘要: A method of manufacturing optical elements, such as for head-up displays, from holographically recorded interference patterns in a dichromatic gelatin is disclosed. The exposed hologram pattern is developed through hydration, the hydrated hologram gelatin is dehydrated by contacting the hydrated gelatin with a mixture of isopropyl alcohol and an inert anhydrous fluid, such as a liquid fluorinated hydrocarbon solution. The dehydrated hologram pattern can then be subsequently stabilized, for example, by baking.

    摘要: A hologram exposure system that includes a holographic recording medium, a holographic prism adjacent the holographic recording medium for most efficiently diffracting light of a predetermined wavelength and at a predetermined incidence angle, a first monochromatic beam directed toward the holographic prism at the predetermined incidence angle, and a second monochromatic beam directed toward the holographic prism at an incidence angle that allows the second monochromatic beam to be transmitted by the holographic prism without any diffraction. The holographic prism diffracts the first monochromatic beam and transmits the second monochromatic beam without any diffraction to produce a diffracted first construction beam and a non-diffracted second construction beam which interfere in the holographic recording medium to form holographic fringes therein. The exposure system further includes a holographic zero order filter interposed between the holographic prism and the holographic recording material for diffracting away from the holographic recording medium a portion of the first monochromatic beam that is not diffracted by the holographic prism.
