Abstract

In this paper, three-dimensional (3D) optical correlation is presented based on binary computer-generated hologram. The 2D input image is divided into some squared blocks, which are placed in 3D space. These blocks are encoded into a phase-only pattern, and the generated phase pattern is further binarized. It is numerically illustrated that high security can be achieved in the system, and decryption result using only one axial position does not contain sufficient information for correct correlation. It is also demonstrated that the binary phase-only pattern can be flexibly generated for the decoding. The 3D optical correlation based on binary computer-generated hologram can effectively enrich 3D optical security area.
