| Title: | Multiple-wavelength double random phase encoding with CCD-plane sparse-phase multiplexing for optical information verification | Authors: | Chen, W | Issue Date: | 20-Dec-2015 | Source: | Applied optics, 20 Dec. 2015, v. 54, no. 36, p. 10711-10716 | Abstract: | A novel method is proposed by using multiple-wavelength double random phase encoding (MW-DRPE) with CCD-plane sparse-phase multiplexing for optical information verification. Two different strategies are applied to conduct sparse-phase multiplexing in the CCD plane. The results demonstrate that large capacity can be achieved for optical multiple-image verification. The proposed optical verification strategy is implemented based on optical encoding, and the keys generated by optical encryption can further guarantee the safety of the designed optical multiple-image verification system. The proposed method provides a novel alternative for DRPE-based optical information verification. | Publisher: | Optical Society of America | Journal: | Applied optics | ISSN: | 1559-128X | EISSN: | 2155-3165 | DOI: | 10.1364/AO.54.010711 | Rights: | © 2015 Optical Society of America.
