| Title: | Computer-generated hologram using binary phase with an aperture | Authors: | Chen, W | Issue Date: | 10-Nov-2017 | Source: | Applied optics, 10 Nov. 2017, v. 56, no. 32, p. 9126-9131 | 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. | Publisher: | Optical Society of America | Journal: | Applied optics | ISSN: | 1559-128X | EISSN: | 2155-3165 | DOI: | 10.1364/AO.56.009126 | Rights: | © 2017 Optical Society of America.
