Abstract

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.
