Wondering what information encoding in five dimensions is about, here's a bit from the abstract: "The two independent parameters describing birefringence, the slow axis orientation (4th dimension) and the strength of retardance (5th dimension), are explored for the optical encoding of information in addition to three spatial coordinates." http://spie.org/PWL/conferencedetails/laser-micro-nanoprocessing#2220600 http://spie.org/PWL/conferencedetails/laser-micro-nanoproces...
