本文对反射型三维散斑移位复用全息存储器的最大存储容量进行了数值研究。在考虑页间串扰噪声的基础上,导出了存储容量的显式表达式。我们制作了一个模拟器,通过计算波的传播、记录全息图以及通过标量衍射重建来评估反射型全息数据存储。我们计算所得的衍射效率,即噪声,在第一个零的散斑移位复用的属性。数值结果表明,存储容量与数值孔径的四次方和记录介质的体积成正比,与波长的三次方成反比。讨论了可扩展存储容量。
Maximum storage capacity in a reflection-type holographic memory with three-dimensional speckle shift multiplexing is investigated numerically. An explicit expression of storage capacity is derived on the basis of interpage crosstalk noise. We fabricate a simulator to evaluate reflection-type holographic data storage by calculating wave propagation, recording a hologram, and reconstruction by scalar diffraction. We calculate the properties of the resultant diffraction efficiency, that is the noise, at the first null in the speckle-shift multiplexing. Numerical results indicate that the storage capacity is proportional to the numerical aperture to the fourth power and to the volume of the recording medium and is inversely proportional to the wavelength to the third power. Achievable storage capacity is discussed.
