Method using holography for the displaying of information or image, for example advertisement

摘要

According to one aspect, the invention relates to a method for displaying information or image hologram comprising the steps of providing a hologram (5) with a holographic representation recorded therein, using a light source (4) to emit light to illuminate said hologram (5) and form a consequent holographic 2D or 3D image, placing said hologram (5) and said light source (4) in an opening below ground level (1), and covering said opening with a transparent material element (2) resistant enough for a viewer (3) to walk on it, the formed holographic 2D or 3D image being made visible through the transparent material element (2).
