Robust Optical Data Encryption by Projection‐Photoaligned Polymer‐Stabilized‐Liquid‐Crystals (Advanced Optical Materials 21/2023)

Robust Optical Data Encryption by Projection‐Photoaligned Polymer‐Stabilized‐Liquid‐CrystalsIn article number 2301364, Xiangfan Chen, Kailong Jin, and co‐workers develop a facile optical data encryption technique utilizing polymer‐stabilized‐liquid‐crystals (PSLCs) combined with projection photoalignment and photopatterning methods. By distributing the essential polarized patterns that constitute the encoded information to paired, environmentally robust, and widely deployable PSLCs, information security is significantly boosted. This work enlightens new design methodologies in LC‐based optical data encryption and anti‐counterfeiting.
