Title:
ホログラフィデータを記憶するための方法
Document Type and Number:
Japanese Patent JP5227322
Kind Code:
B2
Abstract:
A method for storing holographic data, said method comprising: step (A) providing an optically transparent substrate comprising a polymer composition and a light absorbing chromophore, said polymer composition comprising a continuous phase and a dispersed phase, said dispersed phase being less than about 200 nm in size and wherein the refractive index of said dispersed phase exhibits a non-linear response to incident optical intensity; and step (B) irradiating a volume element of the optically transparent substrate with a holographic interference pattern, wherein the pattern has a first wavelength and an intensity both sufficient to cause a phase change in at least a portion of the dispersed phase within the volume element of the substrate to produce within the irradiated volume element refractive index variations corresponding to the holographic interference pattern, thereby producing a optically readable datum corresponding to the volume element.
