A holographic recording medium having a polymer matrix comprising a developer, wherein the holographic recording medium is capable of recording a latent hologram and the developer is capable of developing the latent hologram into a readable hologram by activation of the developer is disclosed. The holographic recording medium is capable of storing large numbers of holograms in the same volume with better signal resolution than previous holographic media by first recording a multitude of latent (or very weak) holograms in the same volume of space, then applying preferably a non-chemical fixing step to develop the latent holograms into readable holograms. The holographic recording medium and method of this invention cause the holograms to increase in diffraction efficiency, thus preventing complications caused during recording of holograms whereby previously recorded holograms interfere with latter recorded holograms in the same volume of space within the media.
A medium comprising a polymer matrix and comprising a developer, wherein the medium is capable of recording a latent hologram and the developer is capable of developing the latent hologram into a readable hologram by activation of the developer.
A method of manufacturing a media comprising mixing a developer to media components and forming the medium, wherein the medium is capable of recording a latent hologram and the developer is capable of developing the latent hologram by activation of the developer.
The method of forming a hologram in a medium comprising recording a latent hologram in the said medium, and developing the latent hologram by activation.
A polymeric matrix that chemically stores a spatial light distribution and comprises a developer, wherein the spatial light distribution is capable of being developed into a spatial refractive index distribution by an action of the developer upon activation of the developer by an energy source.
A method of storing a spatial light intensity pattern in a medium as a refractive index pattern, comprising:
