Angular multiplexing is a process that enables a holographic tag to represent more than a single pattern within a set of spatial coordinates. There are different state of the art techniques for generating angularly multiplexed images within one set of spatial coordinates. It requires sufficient accuracy in order to keep each image quality independently high when creating the structures. Our processing team has perfected the technique via novel implementation of nano-optical solution in combination with firmware controlled patterning technology. The result is storing images with different shapes and sizes and colors within one set of spatial coordinates.
Figure 1. The Plexar tags can vary in shape and size and can portray an organizational logo for visual authentication or commercial purposes. The information stored in them however is only visible to a designated reader device equipped with the proper algorithm and proper readout optics.
