High storage densities using a holographic system are achievable using a stratified medium while maintaining a relatively high selectivity upon reconstruction of the stored images. Such combination of high density and high selectivity is achievable by employing a stratified medium and a recording process where selectivity does not vary with recording thickness.

Holographic process and media therefor

A thick holographic recording medium suitable for use in multiplex holography is prepared from a solution of a bi-functional oligomer and a mono-functional monomer. Precuring, possibly at the same radiation wavelength used for recording, cross-links the oligomer, thereby creating a host for the recording monomer.

Holographic recording

A method for fabricating an article, comprising the steps of grasping an outer surface of a first substrate with a first holder, whereby the outer surface of the first substrate is held to an inner surface of the first holder; grasping an outer surface of a second substrate with a second holder, whereby the outer surface of the second substrate is held to an inner surface of the second holder; arranging the inner surfaces of the first and second holders to face one another in a selected angular relationship; disposing an adherent on one or more surfaces selected from an inner surface of the first substrate and an inner of the second substrate; moving the first and second holders toward each other such that the inner surfaces of the first and second substrates contact the adherent; and at least partially curing the adherent while the inner surfaces of the first and second holders are in the selected angular relationship to form a multilayer article, wherein after removal of the first and second holders the at least partially cured adherent maintains the multilayer article in a posture at which the multilayer article was held by the first and second holders; and a system comprising a multilayer article that comprises a substrate and a layer of at least partially cured adherent adhered to the substrate, wherein the memory cell has surface flatness and transmission flatness values of about 0.05 to about 0.25 waves/cm, and wherein the force exerted by the adherent on the substrate maintains the flatness.
