Abstract: Light modulator displays may be illuminated using a light guide comprising diffractive optics that directs light onto the light modulators. The light guide may comprise, for example, a holographic light turning element that turns light propagating within the light guide onto the array of light modulators. In some embodiments, the holographic element has multiple holographic functions. For example, the holographic element may additionally collimate ambient light or diffuse light reflected form the light modulators.

Abstract: Light modulator displays may be illuminated using a light guide comprising diffractive optics that directs light onto an array of light modulators. A holographic light turning element may be included with the light guide to turn light propagating within the light guide onto the light modulators. In some embodiments, the holographic element is configured to distribute a substantially uniform amount of light across the array of modulators. The holographic element may, for example, have a turning efficiency that changes along the length of the holographic element. A holographic element can also be used to function as a light bar. Such a holographic element may receive light from a light source such as a light emitting diode and distribute the light along a light guide disposed in front of an array of light modulators.

Abstract: A hologram recording film has a hologram image of an object recorded in a volume hologram photosensitive material by holographic duplication and further has a hologram image of an additional information pattern, e.g. a character or an image, recorded superimposedly in the same volume hologram photosensitive material simultaneously with the holographic duplication so that the additional information pattern is reconstructable in a plane with a depth from the hologram plane. Reflection type additional information is recorded in the hologram recording film so as to be reconstructable simultaneously in superimposition with a reconstructed image from the volume hologram. In addition, transmission type additional information that is in mirror image relation to the reflection type additional information is recorded in the hologram recording film so as to be reconstructable simultaneously in superimposition with the reconstructed image from the volume hologram.
