摘要:
Methods for storing holographic data are presented. The method includes providing an optically transparent substrate comprising a thermally active photochemically active polymer composition, the polymer composition including a photochemically active dye and a heat generating chromophore, thermally activating at least a part of a volume element of the optically transparent substrate to increase a quantum efficiency of photochemical conversion of the photochemically active dye into a photo-product, within the at least a part of the volume element and converting at least some of the photochemically active dye to a photo-product, and producing concentration variations of the photo-product within the volume element of the optically transparent substrate, thereby producing an optically readable datum corresponding to the volume element.
