Laser‐Induced Graphene Hologram Reconfiguration for Countersurveillance Multisecret Sharing (Laser Photonics Rev. 17(8)/2023)

Laser-Induced Graphene Hologram Reconfiguration for Countersurveillance Multisecret Sharing In article number 2200805, Xi Chen, Xinyuan Fang, Min Gu, and colleagues demonstrate a laser-induced hologram reconfiguration technology of graphene oxides, which enables countersurveillance optical multisecret sharing. Secret sharing with 26 information channels is achieved. This work explores an all-optical cryptography strategy with lower-cost and higher-efficiency.
