摘要

提出了一种利用同步角复用技术实现大规模全息存储的方法。我们使用氦氖激光(λ = 633 nm),在Slavich公司的PFG-03M全息板上,在一个点上同时记录了72个物体。每个物体都放置在一个圆形的摄影透明片上,每个分开0.94度。这项技术使我们能够同时重建72张图像,而不会产生串扰。在一阶得到的衍射效率为6%。给出了实验结果。

New model for holographic storage by simultaneous angular multiplexing
We describe a technique for holographic storage by simultaneous angular multiplexing to obtain a large-scale holographic memory. We recorded 72 objects at the same time in one point on holographic plate PFG-03M from Slavich Co., using a He-Ne laser (λ = 633 nm). Each object is placed on a circular photographic transparency, separate 0.94 degree each one. The technique allows us simultaneous reconstruction of the 72 images without cross-talk. The diffraction efficiency obtained at order one is 6%. Experimental results are shown.
