We discuss the capacity of parallel-access optical memories based on Fourier-transform computergenerated holography. Emphasis is placed on the fundamental capacity cost associated with Fouriertransform computer-generated holography encoding. Capacity cost is discussed in terms of encoder complexity, memory overhead, and media defect tolerance. Results indicate that a sparse encoding of binary data words that supports minimal hologram area usage is an effective scheme for memories based on Fourier-transform computer-generated holography. These results are independent of computergenerated- holography algorithm and media type.
我们讨论了基于傅里叶变换计算全息术的并行访问光学存储器的容量。重点在于与傅里叶变换计算全息编码相关的基本容量成本。从编码器复杂性、内存开销和介质缺陷容忍度方面讨论了容量成本。结果表明,支持最小全息图面积使用的二进制数据字的稀疏编码是基于傅里叶变换计算全息术的存储器的有效方案。这些结果与计算全息算法和介质类型无关。
