    We present an experimental study on the photopolymer poly(methyl methacrylate) doped with phenathrenequinone molecules. Material characteristics for holographic data storage, including optical characteristics, scattering effect, relation between diffraction efficiency and number of holograms, and exposure schedule for multiple storage, are investigated. An experimental demonstration of multiple storage of digital data pages in a polymer cube is presented. (C) 2003 Society of Photo-Optical Instrumentation Engineers.

    We present our studies on a photopolymer of poly(methyl methacrylate) (PMMA) doped with phenathrenequinone (PQ) molecules. We describe their characteristics for holographic data storage, including photo-sensitivity, material M/#, angular selectivity, dynamic exposure schedule, absorption and scattering effect. Experimental demonstrations on multiple digital data pages stored in a polymer cube are presented.

    We use the scaler diffraction theory to analyze the grating detuning effect in a volume holographic data storage system. The general formulas for describing the two-dimensional distribution of retrieved image under the detuning effect have been derived. In terms of the image uniformity and the pixel shift of the retrieval image, computer simulations are used to perform a quantitative analysis.

    We present our studies on the temperature effect of the grating recorded in a phenathrenequinone (PQ) doped poly(methyl methacrylate) (PMMA) photopolymer. The characteristics for recording a strong single grating have been studied. We find that the main limitation of full utilization of the refractive index modulation of the hologram is caused by the scattering effect. Experimental demonstration of using dark enhancement to enhance diffraction efficiency of a grating is presented.

    We present our studies on the photopolymer of poly(methyl methacrylate) (PMMA) doped with quinone-based molecules for holographic data storage. We discuss the recording mechanism involved with the photoreaction of the. quinone and olefin bonds. Experimental characterizations, including sensitive wavelength, holographic recording and material M/# are also presented.

    In this paper, we present investigations on holographic data storage using photopolymer of poly(methyl methacrylate) (PMMA) doped with phenathrenequinone (PQ) molecules. From the system specifications we derive the material parameters that are required for a data storage system. We present a technique of material preparation for obtaining samples with good optical quality. Then we present material characteristics for holographic data storage, including M/#, sensitivity, and material shrinkage. Experimental demonstration on digital data storage is presented and bit error rate is discussed.
