    摘要: A method for measuring a saturated photorefractive index and a recording time constant to correct the precision includes measuring the diffraction efficiency as a function of time for both phase matching and phase mismatching. The saturated photorefractive index and the recording time constant are verified by substitution into a theoretical formula derived from the Coupled Wave Theory. Thus, the method allows a precise determination of the dynamic range of volume holographic memories and thus their storage capacities. The same procedure can also apply to photopolymers.

    摘要: A method for making shaped information-storage material of photo polymers includes mixing powdery azobisisobutyronitrile (AIBN) and powdery acenaphthenequinone (AQ) into liquid monomers of methyl methacrylate (MMA) and stirring a mixture of the AIBN, AQ, and MMA to form a solution. The azobisisobutyronitrile (AIBN) serves as a thermo polymerization initiator, and the acenaphthenequinone (AQ) serves as a photo polymerization initiator. The solution is filtered to remove the saturated photo polymerization initiator. Then, the filtered solution is poured into a shaping container and heated in the shaping container to make solid, shaped information-storage material of photo polymers. The shaping container is then opened to remove the shaped information-storage material of photo polymers. The shaped information-storage material of photo polymers includes two flat lateral sides.
