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.
