In the final demonstration experiment, we encode 10KB Flash to four data pages, each including 512×512 bits. The data pages are 1:2 pixels matched. These four data pages were stored in a single point in a photopolymer media of Aprilis Corporation by using angle multiplexing method, and successfully retrieved.
