An optical encoding system is developed in the Fresnel domain. A phase-only map is iteratively extracted based on a multiplane phase retrieval algorithm, and multiple plaintexts are simultaneously encrypted. Subsequently, the extracted phase-only map is further encrypted into two phase-only masks based on a non-iterative interference algorithm. During image decryption, the advantages and security of the proposed optical cryptosystem are analyzed. Numerical results are presented to demonstrate the validity of the proposed optical multiple-image encryption method. © 2011 IOP Publishing Ltd. | Source Title: | Journal of Optics | URI: | http://scholarbank.nus.edu.sg/handle/10635/56925 | ISSN: | 20408978 | DOI: | 10.1088/2040-8978/13/11/115401 |
