    • closedAccess   Security authentication using phase-encoded nanoparticle structures and polarized light 

      Carnicer, Artur; Hassanfiroozi, Amir; Latorre Carmona, Pedro; Huang, Yi-Pai; Javidi, Bahram Optical Society of America (2015)
      Phase-encoded nanostructures such as quick response (QR) codes made of metallic nanoparticles are suggested to be used in security and authentication applications. We present a polarimetric optical method able to authenticate ...
