|Issue Date:||Jul-2012||Citation:||Chen, W., Chen, X., Sheppard, C.J.R. (2012-07). Optical image encryption based on phase retrieval combined with three-dimensional particle-like distribution. Journal of Optics (United Kingdom) 14 (7) : -. ScholarBank@NUS Repository. https://doi.org/10.1088/2040-8978/14/7/075402||Abstract:||We propose a new phase retrieval algorithm for optical image encryption in three-dimensional (3D) space. The two-dimensional (2D) plaintext is considered as a series of particles distributed in 3D space, and an iterative phase retrieval algorithm is developed to encrypt the series of particles into phase-only masks. The feasibility and effectiveness of the proposed method are demonstrated by a numerical experiment, and the advantages and security of the proposed optical cryptosystems are also analyzed and discussed. © 2012 IOP Publishing Ltd.||Source Title:||Journal of Optics (United Kingdom)||URI:||http://scholarbank.nus.edu.sg/handle/10635/51003||ISSN:||20408978||DOI:||10.1088/2040-8978/14/7/075402|
