  • Patent number: 10539925
    Abstract: Various embodiments are generally directed to techniques for processing holographic recording media. Some embodiments are particularly directed to processing a raw holographic recording medium into an apodized holographic recording medium. For example, a raw holographic recording medium may include a plurality of photosensitive molecules uniformly distributed throughout that are able to record an interference pattern to create a hologram. However, when a photosensitive molecule is desensitized, such as by exposure to incoherent light, its photosensitivity is lost and the molecule may no longer be able to record an interference pattern of coherent light. Various embodiments described herein may include an apodized holographic recording medium that has been exposed to incoherent light in a manner to desensitize some photosensitive molecules therein such that the remaining photosensitive molecules have a non-uniform distribution.

  • Patent number: 10534114
    Abstract: A substrate-guided holographic diffuser has a light-guide section configured to in-couple light and transmit the light within itself via total internal reflection. It can also have a brightness enhancement section that recycles non-diffracted light within the light-guide section. A hologram section that receives light from the light-guide section has a holographic structure defining acceptance conditions and is positioned relative to the internally reflected light such that the internally reflected light meets the acceptance conditions of the holographic structure. The internally reflected light is out-coupled by the holographic structure as a projected image of light scattered from a diffuser.
