摘　　要：利用光栅莫尔条纹实现角度多重体全息存储系统中精密移动平台的位移检测,有效地削弱该系统寻址的系统误差,提高了全息存储系统的数据读出的准确性。实验中在F_3:LiNbO_3晶体中存储了300幅全息图,各幅全息光栅振幅不仅均匀性好,而且振幅相对较大。This paper introduced an approach which can accurately address in the volume holographic storage system and use Moire fringe to detect the position of linear translation stage in angle-multiple-xing volume storage system. This approach effectively decreased the system error of addressing and greatly improved the access veracity of the volume holographic storage system. As many as 300 holo-grams were stored in the Fe ! LiNbo3 crystal and the images were reconstructed with equal diffraction efficiency.
