A concept - holotag, of an automatic holographic-aided identification label is presented with comparative advantages. Technological challenges met on the concept experimental implementation are reviewed. The label carried information is first transposed with a 2-D interleaved self-correcting spatial coding into a plane binary object patch pattern. Then recorded in the form of a computer generated Fourier hologram, spatially multiplexed- holotag, onto an optical recording material-Digital Paper, laminated and protection covered. Image processing techniques followed by decoding procedures regenerate the original data despite process incurred degradations. |
