摘　　要：推导了光聚物全息存储布拉格偏移与记录角度的关系公式,数值计算的结果与实验符合很好。结果表明,光聚物全息存储的布拉格偏移与记录角度有比较大的关系,对于倾斜光栅,记录过程中参物光夹角越小,布拉格偏移越大。该结果对光聚物高密度全息存储器光路的设计有参考意义。In this paper the relationship of Bragg-mismatch and recording angles of holographic photopolymer is deduced, and compared with the experimental result. It showed that the theory tallied with the experiment well. The result indicated that with the decrease of the angle between reference beam and object beam, the Bragg-mismatch increases, this result is important to the design of photopolymer holographic memory system.
