Multiple-Image Hiding Based on Cascaded Free-Space Wave Propagation Using the Structured Phase Mask for Lensless Optical Security System
A novel optical multiple-image hiding method is proposed based on two cascaded free-space propagation transforms in this paper. With the use of the structured phase mask in the phase retrieval algorithm, a plain image is encoded to only one statistically independent phase-only mask. All retrieved ph...
