Paper Abstract

Embossed stereograms offer a very wide range of image possibilities, including portraits, wide or very small subjects, color control, dynamic effects and computer-generated images. This technique allows the origination of images that are extremely difficult or impossible to copy. It is therefore highly suitable for security purposes. Until now, however, very few stereograms have been put into actual use. This is due to the poor quality so far achieved in small-sized stereograms and to the reliance on expensive, cumbersome shooting systems. Technical breakthroughs in these areas, such as Holoscope®, now make it possible to obtain very high definition stereograms, creating opportunities for their use in the security field.
