Abstract: Computer-generated holograms (CGHs) have attracted more and more attention in some application fields, such as 3D displays, optical security, and beam shaping. In this paper, a strategy is presented for optical information verification based on CGH using binary phase (1 bit) with an aperture. The input is encoded into the cascaded phase-only masks based on CGH via iterative phase retrieval, and one extracted phase mask is binarized in which one part is selected according to an aperture and further embedded into a random binary-phase host mask. It is numerically illustrated that the reconstructed image can be effectively verified when system parameters, such as aperture and phase-only masks, are correctly applied. It is demonstrated that the proposed method can provide a promising strategy for CGH-based optical verification.
