Abstract
A method for decreasing scatter or crosstalk in holographic elements recorded in self-developing media, comprising exposing a photopolymer recording media to a holographic pattern at a first temperature of said photopolymer recording media, wherein monomer diffusion is substantially reduced at said first temperature, and warming said photopolymer recording media to a second temperature wherein monomer diffusion is enabled.

A method for decreasing scatter or crosstalk in holographic elements recorded in self-developing media, comprising:
- exposing a photopolymer recording media to a holographic pattern at a first temperature of said photopolymer recording media, wherein monomer diffusion is substantially reduced at said first temperature;
- and
- warming said photopolymer recording media to a second temperature wherein monomer diffusion is enabled.
A holographic recording apparatus for decreasing scatter or crosstalk in holographic elements recorded in self-developing media, comprising:
- a light source operable to generate a coherent light beam;
- a beam expander operable to expand said coherent light beam into an expanded beam;
- a beam splitter operable to form a first beam and a second beam from said expanded beam, said first beam and second beam intersecting said photopolymer recording media, wherein interference of said first and second beams within said photopolymer recording media is operable to form Bragg planes;
- and
- a temperature controlled enclosure located about said photopolymer recording media, wherein said first and second beams are operable to intersect within said enclosure.
