Holographic data storage (HDS) based on a computer-generated hologram (CGH) technique has been proposed as a promising approach to realize an in-line and simple HDS system. This work focuses on multiplexed recording for CGH-based HDS, and the approach based on the reference wave correlation is introduced to the HDS. For the proposed method, the processes for a CGH design are modified to generate reference waves with different phase distributions for each recording. Since holograms are recorded to the same region in a medium with independent reference waves, recorded data-pages are selectively reconstructed by the corresponding reference wave illuminations. The experimental demonstration confirms the feasibility of the proposed method, and the theoretical characteristic for the number of recordable multiplexed holograms is estimated by the numerical simulation.

基于参考波相关性的复用记录，用于计算机生成的全息数据存储

已经提出了基于计算机生成的全息图（CGH）技术的全息数据存储（HDS）作为一种实现在线简单HDS系统的有前途的方法。这项工作着重于基于CGH的HDS的复用记录，并且将基于参考波相关性的方法引入了HDS。对于所提出的方法，修改了CGH设计的过程，以针对每个记录生成具有不同相位分布的参考波。由于全息图是通过独立的参考波记录到介质中的同一区域的，因此通过相应的参考波照明可以选择性地重建记录的数据页。实验演示证实了该方法的可行性，
