ScholarBank@NUS Repository. https://doi.org/10.1364/OL.35.003817||Abstract:||In this Letter, we propose a method for optical image encryption based on diffractive imaging. An optical multiple randomphasemask encoding systemis applied, and one of the phase-onlymasks is selected and laterally translated along a preset direction during the encryption process. For image decryption, a phase retrieval algorithm is proposed to extract a high-quality plaintext. The feasibility and effectiveness of the proposedmethod are demonstrated by numerical results. The proposed method can provide a new strategy instead of conventional interference methods, and it may open up a new research perspective for optical image encryption. © 2010 Optical Society of America.||Source Title:||Optics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/51002||ISSN:||01469592||DOI:||10.1364/OL.35.003817|
