通过实验和数值研究了具有散斑位移记录的反射型全息图的三维位移选择性。我们构建了一个实验装置,由数值孔径为 0.28 的透镜和厚度为 0.5 mm 的铁掺杂 LiNbO(3) 组成。实验结果表明,三维选择性的衍射效率尺寸为0.97微米×0.97微米×8.8微米。我们还开发了体积全息存储器模拟器来评估实验结果。该模拟器可以定量评估误码率、信噪比和衍射效率。数值结果与实验结果吻合良好。实验和数值结果表明三维移位复用可以增加存储容量。
Three-dimensional shift selectivity of a reflection-type hologram with speckle shift recording is investigated experimentally and numerically. We build an experimental setup consisting of lenses with numerical apertures of 0.28 and an iron-doped LiNbO(3) with a thickness of 0.5 mm. The experimental results show that three-dimensional selectivity has a size of 0.97 microm x 0.97 microm x 8.8 microm in diffraction efficiency. We also develop a volume holographic memory simulator to evaluate the experimental results. The simulator can quantitatively evaluate bit error rate, signal-to-noise ratio, and diffraction efficiency. Numerical results are in good agreement with the experimental results. The experimental and numerical results indicate that three-dimensional shift multiplexing can increase the storage capacity.
